Abstract
In order to study the application of computer digital image processing technology in film and television (FAT) animation visual sensing expression, by studying the principle of digital image processing technology and visual sensing technology, a spatial image adaptive steganography image enhancement algorithm by multiscale filters is proposed to carry out enhancement processing of the original image in FAT production. This algorithm can provide more high‐quality and refined original materials for FAT animation production, which is convenient for FAT animation postproduction to produce higher‐resolution and clear FAT works. Finally, the algorithm is verified. The results show that the spatial image adaptive steganography image enhancement algorithm has high security, and the highest average detection error rate is 25.06%. When α = 0.4, the security of the spatial image adaptive steganography image enhancement algorithm is up to 34.62% and the image distortion rate is low. The established image enhancement algorithm can significantly improve the security of the existing spatial image steganography algorithm under different embedding rates, especially at a high embedding rate; the improvement of the spatial domain steganography algorithm is greater. The proposed steganographic image enhancement algorithm by image preprocessing has higher security and better image enhancement effect.

Computer digital image technology builds a new medium and carrier for artistic creation and connects artistic creation and daily life [1,2,3]
Since rich video production experience, how to better serve film and television (FAT) special effects production and visual communication technology for FAT content is an eternal topic for contemporary FAT producers [5]
With the rapid development of computer image processing technology, the scope of Internet information has gradually changed from graphic communication to image communication, creating conditions for network platforms and radio and television platforms to compete
Summary
Computer digital image technology builds a new medium and carrier for artistic creation and connects artistic creation and daily life [1,2,3]. Television, and animation production are closely related to life. As representatives of the cultural industry, film and television (FAT) are becoming more and more popular for daily consumption by the general public. E development of FAT industries has received more and more attention from consumer groups [4]. In the era of rapid development of FAT animation technology, the visual requirements of movie and television screens have become higher and higher for the movie-watching group. Watching a movie is no longer just about the plot. Aestheticism, shock and other visual effects, and visual impact are the criteria for the audience to judge the quality of a movie [6]. Computer graphics technology is widely used in FAT production of original pictures and image processing by virtue of its refined image processing capabilities [7]
