Human gestures and recognizing faces in natural expressions by considering computer vision techniques on mobile devices

A primary phase now undertaking this issue is to achieve automatic recognition of human actions that are typical. In order to make human-computer interfaces genuinely likely, we need to develop a technology that tracks human effort, body behavior and interpret these movements in an effective way. The goal of the action recognition is to analyze the ongoing events automatically from video data. A reliable system which is capable of recognizing various human actions has many important applications that include surveillance systems, health-care systems, and a variety of systems which involve interactions between persons and electronic devices such as human-computer interfaces.
