Human Action Recognition Using Spatio-Temporal Pyramid Model Based Background Subtraction on Depth Maps

Abstract

In this paper, a background subtraction in region method is proposed to recognize actions and interactions in the video. Firstly, the video is taken and converted into frames. Preprocessing techniques are applied to sampled images for noise reduction. Next, a background subtraction method is used to extract the foreground objects in region units. The combination of the background model, color of the object and movement information are employed to get the region object likelihood. Then, an Improved Adaptive region decision function determines the object regions. Moreover, the human detection method produces a bounding box surrounding a person. Histogram Oriented Gradient (HOG) is used for feature extraction and representation. Finally, Multi class support vector machine (SVM) is the classifier used for classification. Introduction
