Abstract

The invention provides a face feature extraction method and device, equipment and a storage medium. The image processing method comprises the following steps: acquiring a to-be-processed image; inputting the to-be-processed image into the face enhancement model, and performing face enhancement processing on the to-be-processed image through the face enhancement model to obtain an enhanced image, wherein the image quality of the enhanced image is higher than that of the to-be-processed image; and inputting the enhanced image into the face feature extraction model, and performing face feature extraction on the enhanced image through the face feature extraction model to obtain a target feature image. According to the method, the image quality can be improved to a great extent, the image information is increased, when the method is applied to the field of face recognition, due to the fact that the image quality is high, the accuracy of face recognition can be effectively improved, and the method can be better suitable for being applied to face recognition in environments and scenes.

Description

technical field [0001] The present application relates to the technical field of image processing, and in particular, the present application relates to a face feature extraction method, device, equipment and storage medium. Background technique [0002] Existing face recognition algorithms usually use deep learning models and loss functions commonly used in the industry, and are implemented through the following steps: face detection, face alignment, face feature extraction and face feature matching, and the differences between different recognition methods The advantage is often the difference in the loss function. [0003] However, no matter what loss function is adopted, face comparison and recognition are still only based on the information of the input image. When the input image quality is good, a higher accuracy can be achieved. However, when the quality of the input image is poor, such as human faces in surveillance videos (low resolution, high compression, high n...
