Recent work has resulted in methods of crayon stroke generation and cartoon style rendering. In this paper, we propose a stylized form of a glass painting to be used in cartoon rendered scenes and animations. Sand blasted glass is used as

The algorithm generates a crayon texture map, with two crayon textures (illuminated color texture and shadowed color texture) combined into one. The crayon texture is generated using crayon stroke generation technique. The texture is then mapped onto the image in cartoon style using

The user now prefers to visit those sites, which are easy to use. Many different methods have been proposed to measure usability of a website. The quantitative methods focus on the performance measurement of the website whereas the qualitative methods estimate the user's opinion of a website. However none of these specify measurement of the human emotions; the emotional experiences of the user during the website visit. This emotional aspect plays a strong guiding force in the way a user uses the website. In this paper we propose a distinct measure, which combines the qualitative, quantitative factors referred in the literature with rarely mentioned factors such as trust and feature state. The measure thus obtained determines the usability of a website from the user view point .It can be employed to compare usability of different websites.

The filter inputs any arbitrary 2D image and converts it into its equivalent glass painted form. The initial image is processed through various nonphotorealistic rendering stages. The major steps involved in the process include – edge detection and refinement, conversion of image into painted form, changing the appearance of the paints into glass paints and enhancing the image with black colored outlines and crushed silver foil background. The specular effect is also achieved by reflection mapping on per-pixel basis.

Component-based systems achieve flexibility by clearly separating the stable parts of systems (i.e. the components) from the specification of their composition. In order to realize the reuse of components effectively in CBSD, it is required to measure the reusability of components. However, due to the black-box nature of components where the source code of these components are not available, it is difficult to use conventional metrics in Component-based Development as these metrics require analysis of source codes. In this paper, we survey few existing component-based reusability metrics. These metrics give a border view of component's understandability, adaptability, and portability. It also describes the analysis, in terms of quality factors related to reusability, contained in an approach that aids significantly in assessing existing components for reusability.

Determining coupling for Aspect-oriented Systems (AOSs) would assist in the quantification of various software attributes and hence improve quality. This paper presents a new Aspect-oriented System Coupling Metric (COAO), which calculates the coupling for complete aspect-oriented system as a whole, based on the properties of elements and the relationships among them. The process of defining a metric primarily requires a clear, unambiguous definition of basic and relevant concepts related to Aspect-Oriented Programming. As such, first and foremost, novel definitions of basic concepts such as system, element, relation, module and attribute are specified concerning Aspect-Oriented Programming. Subsequently, a metric for Aspect-Oriented System Coupling is proposed. Subsequently, the proposed metric is validated theoretically against Braiand prop...

It is still interesting and challenging to create an integrated system to provide those services. A concrete example of such system is a security gateway with those security and copyright protection functionalities. The article proposes an architecture for a Multimedia Security Gateway Protocol (MSGP) to achieve a multidimensional approach to multimedia security on the Internet and also providing anonymity to both the sender and receiver using watermarking techniques
