Toward real-time implementation of optical flow methods, we present an IIR filter structure suitable for local motion analysis. The motion analysis framework is divided into three steps. A set of velocity tuned filters is first applied to the image sequence. Then, for each pixel, the filter which gives the maximal response is selected. Finally, a segmentation step allows a clustering of pixels according to the previously computed motion index. We only focus on the first step of the method. We present the structure of the proposed IIR filters and show the influence of the parameters on their selectivity |
