Hairstyle generation method and device

Abstract

The embodiment of the invention relates to the technical field of image processing, in particular to a hairstyle generation method and a device. The method is applied to a server with a pre-stored graph library, the graph library includes multiple hairstyle pictures. The method comprises: obtaining a plurality of effective corner points in a hair area of a portrait image and a feature descriptor corresponding to each effective corner point, selecting the feature descriptors matched successfully with the graph library by using the graph library, for each feature descriptor that matches the graph library successfully, obtaining a first region block of an effective corner point corresponding to the feature descriptor in a hairstyle picture corresponding to the feature descriptor and a secondregion block of the effective corner point in a hair region, the first region block overlaying the second region block to obtain an initial hairstyle generation picture, and using a depth neural network to fuse the initial hairstyle generation picture to obtain a final hairstyle generation picture. The method and the device can accurately and flexibly generate a cartoon hairstyle adapted to the user image.
