A Review on Image and Video processing
2007
Image processing is any form of signal processing for which the input is an image, such as photographs or frames of video; the output of image processing can be either an image or a set of characteristics or parameters related to the image. Most image-processing techniques involve treating the image as a two-dimensional signal and applying standard signal-processing techniques to it. Video processing is a particular case of signal processing, where the input and output signals are video files or video streams. Video processing techniques are used in television sets, VCRs, DVDs, video codecs, video players and other devices. In This paper, We present Image and Video processing elements. We also present the current technologies related to Image and Video Processing.

Image and Video Processing: An Introductory Guide
Nowadays, embedded computing is extensively used in electronic devices for to capture process and display digital videos. There was a fantastic evolution from the first television transmission systems till the multi format, multi view and high definition television available today. This chapter will explore several techniques underlying the Digital Television (DT) that made it possible to capture, process, store and broadcast digitized moving pictures. The focus of this chapter will be the Image Processing to compress and decompress video sequences, since this is a critical part of a digital television system. A digitized movie contains also sound and data information which are coded aggregated to the video to form what is called the video stream. The evolution of digital television happened at the same pace of the technological progress, particularly in the electronics domain. In fact, only the huge amount of processing power available in VLSI (Very Large Scale Integrated) circuits enables the implementation of sophisticated algorithms that run in digital television apparatuses. The amount of raw video information to display on a high definition television screen is too big to be transmitted or stored at a reasonable cost. Coding the raw video information in a digital domain allows the video compression, maintaining image quality and reducing the amount of data. With sufficient processing power it is possible to explore the spatial and temporal redundancy that exists in a moving image and reduce more than two orders of magnitude the amount of data to be transmitted. In order to reconstruct the movie a powerful digital system is employed at the receiver side. Nowadays we can afford such system at a cost that made them accessible to everyone. Like that, analog television systems are being replaced by its digital counterpart all over the world. The techniques to compress video are normalized by standards. This chapter will consider the newest standard, the H.264/AVC, also known as MPEG4 part 10 Advanced Video Coding (AVC). The algorithms defined in this standard are discussed in this chapter and the architecture of the developed digital system that implements these algorithms is detailed. The H.264/AVC standard doubles the video compression if compared to its precursor (MPEG2) on the same video quality. Therefore it occupies a smaller bandwidth for transmission, reducing the required storage space. Similarly this advance in compression allows increasing the video picture size while maintaining image quality. The bandwidth reduction makes the H.264/AVC an excellent choice for digital television broadcasters who want to distribute content on High Definition Television (HDTV) or to reduce the cost of carrying conventional Standard Definition (SD) channels. Terrestrial television broadcasting is one of the most popular information spreading mechanisms and has reached several social classes for the last eighty years. It has received several enhancements since its first prototype, and the most recent one was the transition to digital terrestrial television, which is being still implanted in several countries. DT represents a new way of accessing information, enabling the transmission of different types of programs and allowing the use of interactivity between the television station and the viewer. Nowadays, in Brazil the terrestrial television broadcasting system is under gradual transition from the analog PAL-M standard to the ISDB-T (Integrated Services Digital Broadcasting -Terrestrial), also called SBTVD (Brazilian Digital Television System). ISDB-T Standard was adopted by Japan in 2003 and in Brazil in 2007, after receives important technological improvements. Besides promoting the study and development of state-of-the-art technologies, the ISDB-T has adopted H.264/AVC as the standard for broadcasting digital video . This video coding standard is also being included in other terrestrial DT standards like DVB-T and ATSC, as presents Table .

Threshold and Color Histogram Method in Compressed and Uncompressed Video
2013
To elaborate a video in terms of its content, it needs to be partitioned into its smallest visual unit called shot. To segment a video into shots, shot boundary is needed. Here pixel wise difference is adapted for uncompressed and compressed video shot transition detection with adaptive threshold. Color histogram is also used for the cut and dissolve boundary. For cut boundary, traditional threshold technique works well but it fails in some cases like camera flash, fast zooming etc. To improve its performance 2nd derivative method is accepted for cut detection and for the dissolve boundary histogram difference with twin comparison method is used. Pixel intensity based approach is utilized for fade detection. Keywords Pixel wise difference, adaptive threshold color histogram, gradual boundary detection, hard cut detection, shot boundary detection, twin comparison. 1.

Image Enhancement In Video Analytics Systems
Control systems and computers, 2020
Recently, video analytics systems are rapidly evolving, and the effectiveness of their work depends primarily on the quality of operations at the initial level of the entire processing process, namely the quality of segmentation of objects in the scene and their recognition. Successful performance of these procedures is primarily due to image quality, which depends on many factors: technical parameters of video sensors, low or uneven lighting, changes in lighting levels of the scene due to weather conditions, time changes in illumination, or changes in scenarios in the scene. This paper presents a new, accurate, and practical method for assessing the improvement of image quality in automatic mode. The method is based on the use of nonlinear transformation function, namely, gamma correction, which reflects properties of a human visual system, effectively reduces the negative impact of changes in scene illumination and due to simple adjustment and effective implementation is widely used in practice. The technique of selection in an automatic mode of the optimum value of the gamma parameter at which the corrected image reaches the maximum quality is developed.
