Abstract:

With the emergence of RGB-D sensor, depth image information can make up for the poor robustness of human body gesture recognition based on color image under complex environment and light changes. Therefore, it becomes more convenient to use depth information to identify human body gesture. To understand the current development situation of human body gesture recognition, the extensive research is expounded on the basis of existing literature and the latest results from the depth image preprocessing, feature extraction and gesture recognition algorithm. The technical development and the existing difficulties and problems are discussed for future related research.
