Abstract :
In this paper, we propose a system which calculates optical flow in real-time based on multichannel integration using different filters. The multichannel integration refers to the method for calculating more accurate velocity field, but it takes much time to calculate. This calculation time can be shortened by the ingenuity for speeding up including concurrent image capturing and selection of neighboring pixels. Experimental results show that velocity field can be estimated much faster than the conventional method.
