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: 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.
