This paper presents a new framework for human action recognition from depth sequences. An effective depth feature representation is developed based on the fusion of 2D and 3D auto-correlation of gradients features. Specifically, depth motion maps (DMMs) are first employed to transform a depth sequence into three images capturing shape and motion cues. A(More)
Image matching is an important work in the field of computer image processing, the technology aligned same scene of two or more images obtained by different sensors in different or the same imaging conditions to determine the relationship between them. Based on the SURF algorithm, this paper adopts density threshold suppression strategies to reduce number(More)
