Abstract

The invention discloses a method and system for extracting the cover image of an animation work. The extraction method includes drawing frames of animation videos at fixed intervals to obtain several picture frames; using a stored deep neural network to detect and output the character of a specified character in each picture frame The confidence of the rectangular frame where the head and body are located is greater than the confidence of the set threshold; judge whether the specified character is detected in the picture frame according to the confidence of the head and body in the picture frame, and if detected, keep the corresponding picture frame and enter the character Detect the confidence step, otherwise delete the corresponding picture frame; multiply the correction coefficient by the head confidence to obtain the character detection confidence of each picture frame; use the two-dimensional sliding window algorithm in the pixel space domain to extract the minimum cost value in each picture frame Sliding window frame; use the sliding window algorithm to calculate the trust degree of each picture frame; select the set number of picture frames with the highest trust degree, and intercept the sliding window frame corresponding to the minimum cost value in the picture frame as the cover candidate picture.

Description

technical field [0001] The invention relates to an image processing method, in particular to a method and system for extracting a cover image of an animation work. Background technique [0002] As a creative industry combining culture and technology, the animation industry is the most promising sunrise industry in the 21st century. As the main carrier of the animation industry, animation film and television works have flourished globally in recent decades, and excellent film and television works and animation IPs continue to emerge. Among so many IP images, how to quickly and automatically detect and recognize animation characters and generate suitable cover images according to the recognition results has become an important issue in the promotion of animation, film and television works and surrounding culture. The current common cover extraction method is to extract the cover Mainly by traversing all the extracted picture frames, and then comprehensively evaluating quality...
