Abstract

The invention is suitable for the technical field of image processing, and provides a face alignment method, which comprises the following steps: acquiring an initial face image, and acquiring a face component attention feature map corresponding to the initial face image; determining face feature information according to the initial face image and the corresponding face component attention feature map; inputting the face feature information into a preset face alignment network for processing to obtain a first face feature parameter vector output by the preset face alignment network; and obtaining a target face image after alignment of the initial face image according to the first face feature parameter vector. According to the method, the interference of irrelevant information in face alignment is eliminated, and the overall alignment precision of the network is improved; the performance of the face alignment method is not limited to defining a face basic model or template of the 3D model any more, a large amount of training data does not need to be obtained, and when the face alignment method is used, errors are further reduced, and the face alignment precision is improved.

Description

technical field [0001] The present application belongs to the technical field of image processing, and in particular, relates to a face alignment method and device. Background technique [0002] Face alignment is a basic and much-received research hotspot in the field of computer vision. It is the process of aligning key feature points of the face, such as eyes, nose, mouth, and contours. The existing face alignment methods mainly include: using CNN to regress 3D face information, training a relatively complex network to regress a single face, and obtaining 68 2D feature points; by estimating 3DMM (3D Morphable Model) coefficients Reconstruct the 3D information corresponding to a single face, etc. However, the performance of the above methods is limited by the basic face model or template that defines the 3D model, and is limited by the acquisition of a large amount of training data, which makes the above methods prone to errors when used, and cannot be accurately performed...
