Real-time optical flow measurement based on parallel processing with multicore computer
Mao Shimokawa,Teruo Yamaguchi,Hiroshi Harada 제어로봇시스템학회 2011 제어로봇시스템학회 국제학술대회 논문집 Vol.2011 No.10
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.
