Abstract


The cartoon is a plastic arts of painting and other art forms as the main means of expression , which has become one of the today 's favorite form of vector-borne , widely used in TV cartoons , animated movies and games development . Rendering techniques can be divided into two categories : photorealistic rendering and non-photorealistic rendering . Photorealistic rendering technology has been a long history , rather than photorealistic rendering technology in recent years in the field of computer graphics international emerging research topics . Non-photorealistic rendering photorealistic rendering basis , it can make the rendered image the cartoon effect as well as an artistic effect . Cartoon effect draw also belongs to the range of non- photorealistic rendering . Traditional 2D cartoon production relies on assistant animator a lot of boring draw , and thus a natural idea is to make use of the computer to reduce the work of the assistant animators , thereby improving the efficiency of the production of cartoon animation , which is the main objective of this paper . I found that the characteristics of the cartoon is obviously feeling the contours and uniform regional color . Therefore, to achieve an image of cartoon-style rendering four technical issues must be resolved , contour extraction closed outline , region segmentation and image rendering . In this article a reasonable choice and organization of classic cartoon rendering algorithms in image processing , using a ladder degrees operator Sobel operator to extract the outline of the image outline with a threshold , then focus quickly divided the area gives a A method for coloring . Starting from the actual needs of the effect , proposed to make full use of the Sobel operator to extract contours outline closed so that the characteristics of the image boundary widens uniform coloring after the completion of the image smooth processing new ideas , for the color image of the two-dimensional cartoon rendering a new method has opened up a new way .
