Is this how we Roll ?

Certainly Natural User Interface remains incomplete if a smart system can not recognize common human gestures. I wondered if my computer could tell me what action i am performing (like walking, running etc). So i planned to study kind of activity recognition. According to some source on internet “Activity Recognition aims to recognize the actions and goals of one or more agents from a series of observations on the agents’ actions and the environmental conditions.”

Like all most all other Image Processing stuff that involve recognizing stuff from an image, activity recognition also follows three steps:

1) Detection/Segmentation : It is the process in through which we separate required portion (or what I call Object of Concern) from Image. In my case OoC is the human body. I separated (or segmented) this from the image simply using background and foreground subtraction.

2) Classification: This process involves processing the segmented frames using certain parameters or matching with some templates

3) This part majorly deals with reasoning engines. They encode the activity semantics based on the lower level action primitives.
