Cartoon Automatic Bitmap Vector Technology Research

For students in vocational computer graphic design, the use Flash animation to complete an excellent work it requires a lot of fine vector images. If you are good at using professional software tools in the toolbox(Pen Tool, Bezier tool, etc.) for graphics rendering, of course, is the best, especially for beginners, it is not so easy,so do not know students draw vector may consider using the bitmap transfer vector of ways. How will such a bitmap to a vector drawing it? This article is to study the contents. This will combine the region growing method and morphological basis for calculation of the first cartoon bitmap de-noising, etc. pretreatment reuse divided region image segmentation based approach, and get out of its closed borders, the use of B-spline curve fitting description of the boundaries of the vector, vector graphics select a filling way to achieve this kind of image vector solutions.The main contribution of the paper is as follows: 1. It implements a bitmap cartoon automatic vectorization method. From bitmap to vector graphics can be as long as two steps automatically, vectorization process without human interaction. 2.According to the cartoon image features, the use of morphology implement a closed boundary extraction method, more efficient than using Canny edge detection method to avoid the noise. 3. The combined area boundary color information or color information, and the use of scan line seed filling algorithm to achieve this kind of cartoon bitmap vectorization area fills..
