Abstract

A method and device for generating a sketch image, which are used to solve the problems in the prior art that the automatic generation technology of a face sketch image has low accuracy, poor generalization ability and slow sketch image generation speed. The method comprises: obtaining a human face image to be processed; obtaining the facial sketch features in the human face image through the P convolution layers of the first network branch in the pre-trained deep convolutional neural network model, and obtaining the facial structure Sketch map; through the P convolution layers of the second network branch in the deep convolutional neural network model, obtain the hair sketch feature in the face image, obtain the hair texture sketch map; describe the facial structure sketch map and The hair texture sketch image is synthesized to obtain a sketch image of the human face image.

Description

technical field [0001] The present application relates to the technical field of image processing, in particular to a method and device for generating a sketch image. Background technique [0002] Face sketch image automatic generation (sketch portrait automatic generation) refers to the process of automatically generating a face image with a sketch style from an input face image. [0003] The automatic generation technology of face sketch images has important applications in many fields. For example, in the field of public security, the sketch image generated based on the suspect’s ID card photo can be compared with the sketch image drawn based on the description of the witnesses, so as to assist the public security organs to determine the identity of the criminal suspect; in the animation industry and In the field of social networking, it is mainly used for sketching and stylized rendering of photos of people. [0004] The current automatic face sketch image generation t...
