Real-time optical flow measurement based on parallel processing with multicore computer

In this paper we propose an optical flow estimation method based on parallel processing with multicore computer. The multichannel integration method refers to the method of measuring more accurate velocity field, but it takes a lot of processing time for the measurement. We divide the procedure of velocity field calculation into piplined stages, and execute them in parallel with a multicore computer. This method reduces the calculating time, and enables more high speed optical flow estimation. Experimental results show that velocity field can be measured faster than single-core processing.
