Embodiment Construction

[0047] The core of the present invention is to identify the video feature information at the sending end, extract the concerned feature value, send the quantized and encoded feature value to the receiving end, and reconstruct the video information according to the feature value at the receiving end.

[0048] In the technical solution provided by the present invention, firstly, the sending terminal can use the camera to capture the video data of facial expressions or human body movements in real time, and extract the facial expression images or human body movement images through the video frame division operation; processing, so as to improve the recognizability; and then by calculating the image sequence, the corresponding characteristic parameters of facial expressions or human body movements, or corresponding change data are obtained; the above data are quantized and encoded, and transmitted to the receiving end; finally, the receiving end After receiving the data, decode and...

Abstract

The invention discloses an image communication method and system based on facial expression/action recognition. In the image communication method based on facial expression recognition, firstly, an image is collected at the sending end, and the facial area in the image is determined; The facial expression feature parameters in the region are extracted; then the extracted facial expression feature parameters are sent to the receiving end; finally, the receiving end uses the facial expression feature parameters to control the local facial model of the receiving end to pass the The facial model reproduces the facial expression. The application of the present invention can not only enhance user experience, but also greatly reduce the requirement on the information transmission rate of the video bearer network, realize more effective video communication, and is especially suitable for wireless communication networks with limited network bandwidth and capacity.

Description

technical field [0001] The invention is based on the fields of pattern recognition and broadband wireless communication, and particularly relates to the technical fields of facial expression recognition, action recognition, wireless data transmission and expression reconstruction. Background technique [0002] The development of image communication (or video communication) technology has a long history. In the early 1960s, developed countries began to study analog video conferencing systems and gradually commercialized them. In the mid-1980s, the rapid development of large-scale integrated circuit technology, breakthroughs in image coding and decoding technology, and the reduction of channel costs provided good development conditions for video communication to become practical. In the 1990s, the rapid development of computer technology and Internet has accelerated the development of video communication technology. The real rapid development and large-scale deployment of vi...
