This paper discusses the artistic characteristics and innovative applications of ink animation in the era of artificial intelligence, mainly including the preprocessing of ink works, the Extraction of stylistic feature analysis, the internal haloing technique, and the simulation technique of ink painting features. The research methods include image segmentation, object contour and internal separation, and the application of ink stylization techniques. The results show that the improved CIE1976L*a*b* color space transformation and the “kernel-free” region growing method have successfully realized the efficient processing and stylistic feature extraction of ink works. The experiments use the gray scale co-production matrix for texture characterization, and the results show that the extracted stylistic features have a high degree of consistency with the traditional artistic features of ink animation. In addition, the practical expression of terrain ink style is realized by 3D ink rendering technology, which demonstrates the innovative application of ink animation in modern technology.
