Kwang-Yeob Lee, Kyungjin Byun, ETRI · Advanced Science and Technology Letters · 2013
The conventional ORB algorithm is optimized for the hardware implementation. The optimized ORB algorithm is implemented on Zynq-7000 SoC Platform. SURF algorithm that is well known as a feature based algorithm is not suitable in the embedded environment, because it requires lots of calculations in the process. The proposed hardware accelerator reduces approximately 50% of internal memory usage and 25% of hardware logic compared to the conventional SURF accelerator, and it perform above 100 frames per second at 100MHz operation frequency.
