Abstract

Human Action Recognition (HAR) is still considered as a significant research area due to its emerging real-time applications like video surveillance, automated surveillance, real-time tracking and resecue missions. HAR domain still have gaps to cover, i.e., random changes in human variations, clothes, illumination, and backgrounds. Different camera settings, viewpoints and inter-class similarities have increased the complexity of this domain. The above-mentioned challenges in uncontrolled environment have ultimately reduced the performances of many well-designed models. The primary objective of this research is to propose and design an automated recognition system by overcoming these afore-mentioned issues. Redundant features and excessive computational time for the training and prediction process has also been a noteworthy problem. In this article, a hybrid recognition technique called HAREDNet is proposed, which has a) Encoder-Decoder Network (EDNet) to extract deep features; b) improved Scale-Invariant Feature Transform (iSIFT), improved Gabor (iGabor) and Local Maximal Occurrence (LOMO) techniques to extract local features; c) Cross-view Quadratic Discriminant Analysis (CvQDA) algorithm to reduce the feature redundancy; and d) weighted fusion strategy to merge properties of different essential features. The proposed technique is evaluated on three (3) publicly available datasets, including NTU RGB+D, HMDB51, and UCF-101, and achieved average recognition accuracy of 97.45%, 80.58%, and 97.48%, respectively, which is better than previously proposed methods.
