摘要
针对插值放大后的图像存在边缘锯齿化和边缘模糊化的问题,在分析方向扩散模型的基础上,提出了采用彩色自蛇模型取代方向扩散模型并用于对插值放大图像的后处理.实验结果证明了本文提出方法的正确性和有效性.
In allusion to the problem of the blurred edges and jagged edges in the images magnified by interpolation, on the basis of analysis of the Directed Diffusion Model, this paper suggests to adopt Color Self-Snake Model instead of Directed Diffusion Model in the postprocessing of images magnified by interpolation. Comparative experiments showed the improvements of our suggestion.
