Background subtraction is widely used for extracting unusual motion of object of interest in video sequences for various applications. In this paper, the authors propose a fast and flexible approach of object detection based on an adaptive background subtraction technique which also effectively eliminates shadows based on color constancy principle in RGB color space. This approach can be used for both outdoor and indoor environments. Their proposed method of background subtraction makes use of multiple thresholding technique for detecting object of interests for any given scene. Once the moving object has been detected from the complex background, then the shadows are detected and eliminated by considering some environmental parameters.
