Abstract: Human action recognition in videos is a prominent field in image processing research and it is a frequently required technique for many computer vision applications. In this paper, a new novel algorithm for human action recognition is presented. This algorithm depends on aligned motion images (AMIs). Three types of AMIs are used: aligned motion history image (AMHI), aligned motion energy image (AMEI), and aligned gait energy image (AGEI). As a feature, these AMIs are obtained after frame processing, AMI computing, and AMI processing. In order to classify and identify the activity, structure similarity measurement index is applied for first time in human recognition in this paper. The achieved experimental results demonstrate a high level of accuracy and efficiency. These results are very close to the recognition of the human observer since accomplished result is approximately 98.93% by using the AGEI that calculated from a sub sequence of first 33 frames in each video samples.
