Abstract

The invention relates to a stick figure generation method based on a face photo, belonging to the field of image processing. The method comprises steps of collecting a face database, and using an on-line open source database as a training object; training a face recognition and key point detection model by using the collected database; extracting feature points from a real face picture; sketchingthe input picture; positioning and segmenting the face, five sense organs, hair, clothing and the like based on the extracted feature points; smoothing, enhancing, graying and binarizing the segmentedimage; and recombining the processed components to form a final result. Compared with the prior art, the method has the advantages that the five sense organs are positioned more accurately; a large number of samples are not needed for training, and less picture data is needed; the training time is shorter, the requirement for hardware is low, no cost increases; the training model is very sufficient, and error-prone details are avoided; and the method can be provided to chocolate 3D printers for printing and can be widely used.

Description

technical field

[0001] The invention relates to a method for generating stick figures based on face photos, which belongs to the field of image processing. Background technique

[0002] Computer-generated face cartoon portraits or caricature portraits mainly include two methods: one is to exaggerate and deform the outline of the face in the photo, and the other is to cartoonize the texture of the face.

[0003] The exaggerated deformation of the profile of the face in the photo is mainly through the extraction of the profile of the face to obtain the line features representing the face, and then some deformations are performed on the lines to generate a "cartoon line drawing" of the face. For example, in Document 1, Sun Hongyu, Tu Changhe, Meng Xiangxu, based on the transformation and deformation of line drawing style based on shape evolution. Published from: Journal of Computer-Aided Design and Graphics, Vol.18, No.3.

[0004] The second method can further enrich the expr...
