Description

technical field

[0001] The invention relates to the technical field of image processing, in particular to a hair drawing method. Background technique

[0002] In recent years, photography applications on mobile phones have emerged in an endless stream. These applications have functions such as beauty and make-up, which greatly enrich people's life fun and are deeply loved by users. Among the above-mentioned applications, there is an APP specially designed for portrait hair treatment to achieve further beauty and makeup effects. However, the existing methods for portrait hair processing are relatively simple, either directly replacing the original hair with new hair materials, or simply changing the color of the original hair. Unsatisfactory, can not meet the needs of users.

[0003] The solution to the above problems is to finely draw the hair of the original portrait as required. In the prior art, there are also algorithms with better hair rendering effects, for example,...
