Smile recognition method and device for a human face image

Abstract

The invention discloses a smiling face recognition device of a human face image, comprising: an image recognition extraction unit, which is used to detect the position of a human face for a plurality of person images that require smiling face recognition, identify and extract the human face images therein, and then send To the image preprocessing unit; the image preprocessing unit is connected with the image recognition extraction unit; the network establishment unit is used to establish a convolutional neural network; the network training unit is respectively connected with the network establishment unit and the image preprocessing unit; identification judgment The unit is respectively connected with the network training unit and the image preprocessing unit, and is used for operating smiley face recognition. In addition, the invention also discloses a smiling face recognition method of a human face image. The present invention can quickly and effectively identify and judge smiles in a large number of face pictures while ensuring high-quality smile recognition on face pictures, meet the user's requirements for smile recognition functions, improve user work efficiency, and save people precious time.

Description

technical field [0001] The invention relates to the technical fields of pattern recognition and computer vision, and in particular to a method and a device for recognizing a smiling face of a human face image. Background technique [0002] At present, with the continuous development of human science and technology, face recognition technology is becoming more and more popular in people's daily life. No matter in artificial intelligence research or public security applications, face recognition technology has always been a cutting-edge and popular technology. status. [0003] Among them, smiley face recognition in face recognition technology is a very important content in the field of computer vision technology. With the growth of application requirements such as face payment, emotion analysis, and medical monitoring, smiley face recognition is an important part of completing human-computer interaction. The components have gained more and more people's attention, which has p...

AI Technical Summary

Problems solved by technology

However, these hand-designed low-level feature expressions cannot express the expression information contained in the face well, and the recognition speed is low, it takes more time, and the recognition accuracy is poor, so it is not conducive to the realization of smile recognition. It cannot meet the user's demand for the smiley face recognition function, which seriously reduces the user's experience
