Overview of Input-based Facial Expression Generation and Latest Applications

Expression generation technology is an important part of the field of artificial intelligence research. As a hot issue in computer applications today, its results have been widely used in human-computer interaction, digital entertainment, communications, video conferencing, and medical fields.This article summarizes the published research methods based on input methods into image and text input control expression generation methods, and reviews them. The image input control expression generation method is divided into two cases according to the presence or absence of constraints. Most model algorithms propose solutions to improve the coincidence of natural images and application models in pixel space. This article discusses typical successes in terms of theory, technology, etc., analyzes the characteristics of different algorithms, current problems, and future development directions, and provides references for related research.
