An HMM segmentation method based statistical layered model for an image of vehicle

An HMM segmentation method based statistical layered model for an image including interest vehicle is brought forward. In statistical layered model, the interest vehicle is called foreground layer and other moving object is called background layer and shadow of moving objects is called shadow layer and is expressed by the statistical model respectively. The model parameters are estimated by the HMM-based method of video sequences. HMM- based method makes use of the spatial relativity and time relativity of video sequences to accomplish recognition of model. The experimental results show that this method can succeed segmenting the moving vehicle.
