基于FPGA的稠密光流计算系统
FPGA-based dense optical flow computing system
摘要
Abstract
High-quality algorithms for dense optical flow computation are computationally expensive, which limits their usability in real-world applications. In order to solve this problem, the hardware accelerator is applied for a high-quality dense optical flow algorithm by CBG(Combined-Brightness-Gradient)model, based on fine-grained parallelisms of FPGAs (Field Programmable Gate Arrays). Experimental results show that 40 frame/s can be processed in time when the working frequency is 200 MHz and the image size is 316×252. Furthermore, optical flow fields for all pixels instead of selected areas are computed for designing.关键词
