Abstract

The invention discloses method, equipment and system for processing image. An image is captured by shooting the same scene by a plurality of cameras distributed at different positions. The method comprises the following steps: detecting face images in the captured image; with different pose angles, processing each detected face image by using a face pose model determined in advance, then generating synthetical images of different pose angles, and taking the synthetical images as synthetical image sets of the corresponding face images; extracting the characteristic vectors of the synthetical image in the synthetical image sets; calculating the distance between different synthetical image sets by calculating the characteristic vector distance between the synthetical images in different synthetical image sets; and clustering the detected face images based on the distance between different synthetical image sets. The method, equipment and system can easily detect and extract the high-quality face images.

Description

technical field [0001] The present invention relates to face image processing, in particular to a method, device and system for processing face images from multiple cameras so as to cluster them. Background technique [0002] Face detection is a hot topic in pattern recognition research and development. In the past few years, face detection technology has been greatly developed in terms of detection accuracy and detection speed. The purpose of face detection is to determine whether there are areas containing human face images in the image and automatically locate these areas of human face images. Face detection is widely used in various fields of life. For example, in recent years, face detection has been embedded in digital cameras to help people obtain high-quality images for human faces using automatic face detection technology. In addition, in security applications, face detection technology is used to extract face images and provide the extracted face images to a fac...
