Image-based person recognition method, device and computer-readable storage medium

Abstract

The invention discloses an image-based person identification method, device and computer-readable storage medium. The method includes: acquiring an image to be identified; image-cutting the to-be-identified image to obtain a plurality of sub-images; Perform face feature extraction on each of the multiple sub-images to obtain at least one face feature map; and perform resolution enhancement processing on each face feature map in the at least one face feature map , obtain the high-resolution face feature map corresponding to each face feature map; perform face recognition on each high-resolution face feature map in the high-resolution face feature map to obtain face recognition result. The present invention can effectively deal with the person identification of the low-resolution images caused by the loss of picture information after coding and compression, so as to fully satisfy the person identification of the pictures crawled from the webpage.

Description

technical field [0001] The present invention relates to the technical field of image recognition, in particular to an image-based person recognition method, device and computer-readable storage medium. Background technique [0002] With the development of Internet of Things technology, it has become a mature technology to identify the identity of people in news pictures by performing face recognition on news pictures; Most of these open source face data have high resolution, and the context of the image is easy to extract. Therefore, the existing pre-trained models for face detection and recognition can effectively deal with high-resolution images transmitted through non-web pages. [0003] However, at present, most of the news pictures are obtained through web crawling. Due to the transmission compression, the image edge information and the semantic expression of the pixels in the local area of ​​the face will be missing, resulting in the loss of the face target information...

Problems solved by technology

[0004] In order to solve the problem that the current picture person recognition method can only target high-resolution images transmitted by non-webpages, but cannot perform person recognition on pictures crawled from webpages, the purpose of the present invention is to provide a method that can identify people in pictures crawled from webpages. Identification method, device and computer-readable storage medium for effective identification of persons
