The traditional fuzzy enhancement method has the problem that the definition of the processed animation image is not good in practical application. Therefore, the computer vision technology is introduced to optimize the fuzzy enhancement method of the animation image details. The method comprises the following steps of: firstly, acquiring detail features of an animation image, and constructing a mathematical model of the animation image; secondly, replacing dark primary colors in the animation image by using prior atlas knowledge, and realizing detail color attenuation processing of the animation image; thirdly, segmenting fuzzy edge information of the animation image based on a computer vision technology; and finally, completing detail fuzzy enhancement processing of the animation image by using a dark channel prior method of guided filtering. The experimental results show that the new method can effectively improve the clarity of animation images, and the efficiency of fuzzy enhancement processing of animation image details has also been greatly improved.
