Embodiment Construction

[0031] The conditional generation confrontation network is an improved form of the generation confrontation network. Both the generator and the discriminator add an additional information as a constraint condition. During the training process, the model is allowed to learn a variety of sample generation processes of different classifications, and different types are generated according to the constraints. An object of the specified class. Researchers have applied it to the face aging synthesis algorithm and achieved good results. However, due to the different expression methods of sketch and photo images, sketch images contain more texture information, and the same algorithm directly applied to sketch images will make the generated aging sketch images too smooth, and some local texture features are difficult to show.

[0032] The attention mechanism draws on the selective attention mechanism of human vision, and the purpose is to select information that is more critical to the...

Abstract

The invention discloses a face sketch image aging synthesis method, which is characterized by comprising the following steps of inputting a target sketch image into a pre-trained attention coding confrontation network model, and determining the aging sketch images of faces in the target sketch image at different age groups.The training process of the pre-trained attention coding adversarial network model comprises the steps of obtaining the plurality of sketch images, wherein the ages and genders corresponding to faces on the sketch images are uniformly distributed; and inputting the sketch images into an attention coding confrontation network model for training to obtain a pre-trained attention coding confrontation network model.

Description

technical field [0001] The invention relates to a face sketch image processing method. Specifically, it relates to an aging synthesis method, device and storage medium based on face sketch images. Background technique [0002] Face aging synthesis algorithm has attracted many scholars' research interest due to its wide applicability and great challenge. However, as a branch of face aging synthesis, face sketch image aging synthesis is rarely studied. In fact, this algorithm also has many application fields, typically in the field of public security. For example, when a lost child or a fugitive is not found for a long time, the face sketch image aging synthesis can update the sketch image at hand of the police, thereby helping the police find the missing child or fugitive. [0003] The existing face sketch image aging synthesis techniques include methods based on heterogeneous image transformation and methods based on data-driven. The method based on heterogeneous image co...
