A method and apparatus for color a contour map

Abstract

The invention discloses a method and a device for coloring a contour map. The method comprises the following steps: obtaining a contour map to be colored and required color elements; Based on the contour map and color elements, a color map is generated by coloring the contour map with a pre-established generation network. The feature matching loss of color image relative to the real color image iscalculated by matching the generated color image with the real color image based on the pre-established discriminant network. If the calculated feature matching loss satisfies the first preset condition, the generated color map is taken as the color map obtained by coloring. If the calculated feature matching loss does not satisfy the first preset condition, the generating network is updated, andthe color map is regenerated by the updated generating network using the contour map and the color elements, and the subsequent steps are carried out until the calculated feature matching loss satisfies the first preset condition. Compared with the prior art, the contour map coloring method and the device of the invention can achieve better coloring effect.

Description

technical field [0001] The invention relates to the field of image processing, in particular to a contour map coloring method and device. Background technique [0002] With economic development, people's living needs no longer stay at the level of food, clothing, housing and transportation, but pay more and more attention to spiritual and cultural needs. In recent years, my country's comics industry has developed rapidly, but compared with Japan and the United States, which are major exporters of comics, more efforts are needed to reform and innovate domestic comics. [0003] In the prior art, the comic outline of black and white sketches is colored. In the patent document whose patent publication number is CN107578367A and the patent name is "a method and device for generating stylized images", it is disclosed to use the generative confrontation network ( Generative adversarial networks, GAN), generate a color map based on the image drawn by the user, so as to further perf...

AI Technical Summary

Problems solved by technology

However, in this method, the color map is generated by the generative confrontation network for the drawing map, which cannot achieve a good coloring effect.
