Abstract: The human action recognition has large number of applications in various domains however its applicability in many real time scenarios has been restricted due to the speed of action recognition algorithms. Therefore, there is great need to develop the faster action recognition algorithm. To address this constraint we present a hybrid algorithm for speeded human action recognition (SHAR) based on action snippets algorithm and neighborhood component analysis. The action snippet algorithm results in filtering the key frames and eliminating less informative frames. Moreover, the feature selection algorithm at further stage of recognition helps to trimmed down the length of feature vector massively. These two algorithms are integrated with standard pair of feature extraction and classification at different stages to accomplish the goal of faster recognition without compromising the recognition accuracy. The performance of proposed algorithm has been evaluated on weizmann dataset. The proposed methodology provides overall recognition accuracy of 90% with four times faster classification over standard approach of feature extraction followed by classification.
