... pixels in a frame, we make another sparsity assumption on the foreground. Assumption 2. The candidate foreground x F of a frame is sparse after background subtraction. 3.2. Background Subtraction. ... group sparse as similar as [13, 14]. However, the difference is that we also assume the background to have a sparse representation and learn a dic- tionary to characterize the b...
