In this paper, we investigate the problem of video classification into predefined genre. The approach adopted is based on spatial and temporal descriptors derived from short video sequences (20 seconds). By using support vector machines (SVMs), we propose an optimized multiclass classification method. Five popular TV broadcast genre namely cartoon, commercials, cricket, football and tennis are studied. We tested our scheme on more than 2 hours of video data and achieved an accuracy of 92.5%.

Internet users spend an amount of time on videos and their needs have generated tremendous amount of data .However ,too many videos are quite difficult for human beings to categorize and labelling it .As of today ,a significant human effort is needed to categorize these video data file that could substantially help the people to reduce the growing amount of clustering video data on Internet .The main objective of this project is to create a model to categorize and label the videos automatically with the help of SVM methods .As the result of this project we can able to classify the videos without any predefined class labels .We achieved classification accuracy of approximately 90 % on the test set which is a decent result considering the relative simplicity of the model. A proposed system is to identify the video belongs to which category using machine learning model. Our base idea is to collect the common features vectors from various videos dataset. Then we use Support Vector Machine algorithm to train our model to detect the video classification.

We investigate the problem of automated video classification by analysing the low-level audio-visual signal patterns along the time course in a holistic manner. Five popular TV broadcast genre are studied including sports, cartoon, news, commercial and music. A novel statistically based approach is proposed comprising two important ingredients designed for implicit semantic content characterisation and class identities modelling. First, a spatial-temporal audio-visual "concatenated" feature vector is composed, aiming to capture crucial clip-level video structure information inherent in a video genre. Second, the feature vector is further processed using principal component analysis to reduce the spatial-temporal redundancy while exploiting the correlations between feature elements. This gives rise to a compact representation fro effective probabilistic modelling of each video genre. Extensive experiments are conducted assessing various aspects of the approach and their influence on the overall system performance.

The performance of video automatic classification algorithm depends largely on the extraction of video features and selection of classification algorithm. From the perspective of video contents and video style type, the paper presents a new feature representation scheme, i.e. MPEG-7 visual description sub-combination model, a new method based on support vector machine (SVM) to solve problems with existing algorithms, by analyzing visual differences between five types of videos. Also we improve the classifier decision scheme and then propose the secondary prediction mechanism based on SVM 1-1 approach, improving the accuracy of SVM multi-classification method. The experimental results indicate that the proposed method manifests differences of different videos about feature selection, enhances the discrimination ability of videos pending for classification and increases the effectiveness of SVM multi-video classification.

This paper presents a genre-specific modeling strategy capable of improving the task of content based video classification and the speed of data retrieval operations. With the ever increasing growth of video data it is important to classify video shots into groups based on its content. For that reason, it is of primary concern to design systems that could automatically classify videos into different genres based on its content. We consider the genre recognition task as a classification problem. We use support vector machines to perform the classification task and propose an improved video classification method. The experimental results show that genre-specific modeling of features can significantly improve the performance. Results have been compared with two contemporary works on video classification, to demonstrate the superiority of our proposed framework.
Video Classification has been an active research area for many years. Video Classification algorithms can be broadly classified into two types. The first type of classifier is a category specific video classifier, which classifies video from a particular category such as sports into categories such as tennis, baseball. The second type of classifier is a generic video classifier, which classifiers the videos into generic categories, such as sports, commercials, news, animation etc. This work aims at generic video classification and exploits motion information and cross correlation measure for classification.

We present a new approach for classifying mpeg-2 video sequences as 'sport' or 'non-sport' by analyzing new high-level audiovisual features of consecutive frames in real-time. This is part of the well-known video-genreclassification problem, where popular TV-broadcast genres like cartoon, commercial, music video, news and sports are studied. Such applications have also been discussed in the context of MPEG-7 [1]. In our method the extracted features are logically combined by a support vector machine [2] to produce a reliable detection. The results demonstrate a high identification rate of 98.5% based on a large balanced database of 100 representative video sequences gathered from free digital TV-broadcasting and world wide web.

Patel College of Engineering & Technology, Gujarat, India ---------------------------------------------------------------------------***--------------------------------------------------------------------------Abstract Video classification literature has been reviewed and techniques for the same are provided here in this paper. Classification process in general requires features based on which one can distinguish among the categories. These features are mainly taken from text, audio or visual content of the video. Based on that mainly three classification techniques are there as discussed here. Based on the application user has to select the method and features. Pros and cons of each method are mentioned in this paper with suitable applications.

We address the issue of automatic video genre retrieval. We propose three categories of content descriptors, extracted at temporal, color and structural level. At temporal level, video content is described with visual rhythm, action content and amount of gradual transitions. Colors are globally described with statistics of color distribution, elementary hues, color properties and relationship. Finally, structural information is extracted at image level and histograms are built to describe contour segments and their relations. The proposed parameters are used to classify 7 common video genres, namely: animated movies/cartoons, commercials, documentaries, movies, music clips, news and sports. Experimental tests using several classification techniques and more than 91 hours of video footage prove the potential of these parameters to the indexing task: despite the similarity in semantic content of several genres, we achieve detection ratios ranging between 80 − 100%.

Video classification is the first step toward multimedia content understanding. When video is classified into conceptual categories, it is usually desirable to combine evidence from multiple modalities. However, combination strategies in previous studies were usually ad hoc. We investigate a meta-classification combination strategy using Support Vector Machine, and compare it with probability-based strategies. Text features from closedcaptions and visual features from images are combined to classify broadcast news video. The experimental results show that combining multimodal classifiers can significantly improve recall and precision, and our meta-classification strategy gives better precision than the approach of taking the product of the posterior probabilities.
How to achieve the goal of automatically classifying video shots by their content is still an issue under debate. In this paper we present a novel set of low-level descriptors for the classification of TV video shots into meaningful semantic classes which can then be useful when browsing a TV stations archives. The motion features we propose consist of a modified Perceived Motion Energy Spectrum descriptor for local motion and a Normalized Dominant Motion Histogram for camera motion. Since exclusively motion-based classification has a very limited applicability, we also add three normalized local HSV histograms, extracted from particular key-frames we select with a simple yet efficient approach, as color descriptors. Our experimental implementation is tested on real-world TV video shots using a binary classifier based on Support Vector Machines and the results demonstrate that the proposed features can achieve high success rates not only on narrow and specialized classes, but also on more generic ones.

This paper presents a set of computational features originating from our study of editing effects, motion, and color used in videos, for the task of automatic video categorization. These features besides representing human understanding of typical attributes of different video genres, are also inspired by the techniques and rules used by many directors to endow specific characteristics to a genre-program which lead to certain emotional impact on viewers. We propose new features whilst also employing traditionally used ones for classification. This research, goes beyond the existing work with a systematic analysis of trends exhibited by each of our features in genres such as cartoons, commercials, music, news, and sports, and it enables an understanding of the similarities, dissimilarities, and also likely confusion between genres. ClassiJication results from our experiments on several hours of video establish the usefulness of this feature set. We also explore the issue of video clip duration required to achieve reliable genre identification and demonstrate its impact on classification accuracy.

We present a new approach for classifying mpeg-2 video sequences as 'cartoon', 'commercial', 'music', 'news' or 'sport' by analyzing specific, high-level audio-visual features of consecutive frames in real-time. This is part of the well-known video-genre-classification problem, where popular TV-broadcast genres are studied. Such applications have also been discussed in the context of MPEG-7 [1]. In our method the extracted features are logically combined using a set of classifiers to produce a reliable recognition. The results demonstrate a high identification rate based on a large representative collection of 100 video sequences (20 sequences per genre) gathered from free digital TVbroadcasting in Europe.
At present, so much videos are available from many resources. But viewers want video of their interest. So for users to find a video of interest work has started for video classification. Video Classification literature is presented in this paper. There are mainly three approaches by which process of video classification can be done. For video classification, features are derived from three different modalities: Audio, Text and Visual. From these features, classification has been done. At last, these different approaches are compared. Advantages and Dis-advantages of each approach/method are described in this paper with appropriate applications.

Video content is evolving enormously with the heavy usage of internet and social media websites. Proper searching and indexing of such video content is a major challenge. The existing video search potentially relies on the information provided by the user, such as video caption, description and subsequent comments on the video. In such case, if users provide insufficient or incorrect information about the video genre, the video may not be indexed correctly and ignored during search and retrieval. This paper proposes a mechanism to understand the contents of video and categorize it as Music Video, Talk Show, Movie/Drama, Animation and Sports. For video classification, the proposed system uses audio and visual features like audio signal energy, zero crossing rate, spectral flux from audio and shot boundary, scene count and actor motion from video. The system is tested on popular Hollywood, Bollywood and YouTube videos to give an accuracy of 96%.

In recent years, there has been a rapid development in web users and sufficient bandwidth. Internet connectivity, which is so low cost, makes the sharing of information (text, audio and videos) more common and faster. This video content needs to be analyzed for prediction it class in different purpose for the users. Many machines learning approach has been developed for the classification of video to save people time and energy. There are a lot existing review papers on video classification, but they have some limitations such as limitation of analysis, badly structured, not mention research gaps or findings, not clearly describe advantages, disadvantages, and future work. But our review paper almost overcomes these limitations. This study attempts to review existing video-classification procedures and to examine the existing methods of video-classification comparatively and critically and to recommend the most effective and productive process. First of all, our analysis examines the classification of videos with taxonomical details, latest application, process and datasets information. Secondly, overall inconvenience, difficulties, shortcomings and potential work, data, performance measurements with the related recent relation in science, deep learning and the model of machine learning. Study on video classification systems using their tools, benefits, drawbacks, as well as other features to compare the techniques they have used also constitutes a key task of this review. Lastly, we also present a quick summary table based on selected features. In terms of precision and independence extraction functions, the RNN(Recurrent Neural Network), CNN(Convolutional Neural Network) and combination approach performs better than the CNN dependent method.

In this paper, we propose an audio-visual approach to video genre categorization. Audio information is extracted at block-level, which has the advantage of capturing local temporal information. At temporal structural level, we asses action contents with respect to human perception. Further, color perception is quantified with statistics of color distribution, elementary hues, color properties and relationship of color. The last category of descriptors determines statistics of contour geometry. An extensive evaluation of this multi-modal approach based on on more than 91 hours of video footage is presented. We obtain average precision and recall ratios within [87% − 100%] and [77% − 100%], respectively, while average correct classification is up to 97%. Additionally, movies displayed according to feature-based coordinates in a virtual 3D browsing environment tend to regroup with respect to genre, which has potential application with real content-based browsing systems.

The problem addressed here is classification of videos at the highest level into pre-defined genre. The approach adopted is based on the dynamic content of short sequences (30 secs). This paper presents two methods of extracting motion from a video sequence: foreground object motion and background camera motion. These dynamics are extracted, processed and applied to classify 3 broad classes: sports, cartoons and news. Experimental results for this 3 class problem give error rates of 17%, 8% and 6% for camera motion, object motion and both combined respectively, on 30 second sequences.
Videos are in huge demand today. The internet is flooded with videos of all types like movie trailers, songs, security cameras etc. we can find so many genres but the only difficulty we face is the proper search of these videos. Sometimes we are irritated and get sick of the irrelevant search result. To sort out this difficulty we aim to classify videos on the basis of different attributes. Here in this paper we survey the video classification literature. Much work has been done in this field and much is awaited. We describe the general features chosen and summarize the research in this area. We conclude with ideas for further research.

We propose an audiovisual approach to video genre classification using content descriptors that exploit audio, color, temporal, and contour information. Audio information is extracted at blocklevel, which has the advantage of capturing local temporal information. At the temporal structure level, we consider action content in relation to human perception. Color perception is quantified using statistics of color distribution, elementary hues, color properties, and relationships between colors. Further, we compute statistics of contour geometry and relationships. The main contribution of our work lies in harnessing the descriptive power of the combination of these descriptors in genre classification. Validation was carried out on over 91 hours of video footage encompassing 7 common video genres, yielding average precision and recall ratios of 87%−100% and 77%−100%, respectively, and an overall average correct classification of up to 97%. Also, experimental comparison as part of 1 the MediaEval 2011 benchmarking campaign demonstrated the superiority of the proposed audiovisual descriptors over other existing approaches. Finally, we discuss a 3D video browsing platform that displays movies using feature-based coordinates and thus regroups them according to genre.
