Smile face recognition method and device for human face image

Abstract

The invention discloses a smile face recognition device for a human face image, and the device comprises an image recognition and extraction unit which is used for detecting the positions of human faces in a plurality of to-be-recognized human face images, extracting the human face images from the plurality of to-be-recognized human face images, and transmitting the human face images to an image preprocessing unit; the image preprocessing unit which is connected with the image recognition and extraction unit; a network building unit which is used for building a convolution neural network; a network training unit which is connected with the network building unit and the image preprocessing unit; and a recognition and judgment unit which is connected with the network training unit and the image preprocessing unit, and is used for the recognition of human faces. In addition, the invention also discloses a smile face recognition method for the human face image. According to the invention, the device and method can quickly and effectively carry out the accurate recognition and judgment of smile faces in a large number of human face images while guaranteeing the high-quality smile face recognition of the human face images, meet the requirements of a user for a function of smile face recognition, improves the work efficiency of the user, and saves the precious time for the user.

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...

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
