Vector graphics plays an important role in computer animation and imaging technologies. However present techniques and tools
cannot fully replace traditional pencil and paper. Additionally, vector representation of an image is not always available.
There is not yet a good solution for vectorizing a picture drawn on a paper. This work attempts to solve the problem of vectorizing
grayscale line drawings. The solution proposed uses Disk B-Spline curves to represent strokes of an image in vector form.
The algorithm builds a vector representation from a grayscale raster image, which can be a scanned picture for instance. The
proposed method uses a Gaussian sliding window to calculate skeleton and perceptive width of a stroke. As a result of vectorization,
the given image is represented by a set of Disk B-Spline curves.

    ABSTRACT: Research objective and hypotheses: "Scholarly research in the field of South East Asian animation has resulted in findings that acknowledge the lack of original and genuinely Southeast Asian animation concepts, which are not derived from Western or Japanese styles."Error! Reference source not found. This research project sets out to create innovative and genuinely Southeast Asian digital animation using a traditional Asian story. The investigators argue that this approach will result in animation that distinguishes itself by its strong cultural identity and achieves stylistic innovation. Hassan Muthalib, a renowned Malaysian animation scholar and president of the Animation Society of Malaysia supports this point of view by stating the following: "Congratulations on your effort to explore an area not yet attempted. So far, only literary writers and researchers have forwarded suggestions for the preservation of the nation's folktales, legends and mythologies through feature films but nothing has materialized in a big way."[2]. Methodology and outcomes: Technology and art collaborate in search of a genuinely Asian animation design style: In his research, Hans-Martin Rall has explored Asian folk tales in storyboards and the development art for animated short films. In an interdisciplinary project with computer scientists Hock Soon Seah and Henry Johan, a sequence from the Vietnamese folk-story story The Beach Boy has been fully completed: The collaborators investigated new technological approaches inspired by Asian design. This involved recreation of typical Asian art styles through the use of digital technology by research and use of non photo-realistic rendering, vector and pixel-based automated inbetweening, and mixed media techniques. The investigators were particularly interested in the creation of non-photorealistic styles for the animation of natural phenomena.

    ABSTRACT: Film-making is a high-investment, high-risk industry. We aim to define a framework to bring about a new socio-cultural phenomenon which we call Social Film-Making, bringing part of the film-making process into the digital home community. A wider group of people can be involved via their digital homes to participate in the various stages of film-making to contribute their creative ideas much like the practice of Wikipedia. By connecting people, we want to transform the film industry into a low-investment, low-risk industry and thus bringing film-making accessible to everyone. In this paper, we present only our work on Social Net Coloring, which is a apart of our Social Film-Making project, to enable project managers and artists to color large amount of digital frames in a web-mediated platform that provides excitement, efficiency and flexibility in the film-making process.

    ABSTRACT: Curve extension is a useful function in CAD systems. Disk B-Spline curve has its distinct advantages in representing a 2D region. This paper presents an algorithm for extending the disk B-Spline curve with G2 continuity. A disk Bezier segment is used to construct the extending part and G2-continuity can be used to describe the smoothness at the joint disk. Fairness of the extending disk Bezier curve segment is achieved by minimizing energy objective functions for the center curve and the radius function separately. New control disks are computed by unclamping algorithm to represent the whole extended disk B-Spline curve. The experimental results demonstrate the effectiveness of our method.
