【正文】 physical resource. Aiming at make the photo to be cartoon, this paper briefly describes the development background and environment of the way to deal with photos by matlab. Perform the following operations while ensuring the image without changing the core structure of the case: 1. Based on needs, a bilateral filter to select the image is filtered, in order to remove noise and improve image quality for the purpose of convenience feature extraction. 2. By paring withe RGB color space and Lab color space, choose the better one to achieve color quantization， and reduce the colors in the image. 3. According to the needs of marginal integrity and speed, Dog operator is used to do edge detection, then make the edge stronger and use imopen and imclose. Finally to make the image seems to be cartoon, and realize of nonphotorealistic rendering. Compare with other existing similar methods, we can sum up that this paper achieve making the photo to be cartoon. Keywords: Nonphotorealistic rendering, Bilateral filter, Color quantization, edge detection. 1 目錄 目錄 摘要 ...........................................................................................................................................
