When tracking large numbers of features in high definition video, the KLT feature tracker does not execute in close to real-time. In order to remedy this, the KLT feature tracker has been implemented on a GPU. However, the GPU requires high energy costs. The FPGA is a low power device that can be used to accelerate programs. This research focuses on accelerating the KLT feature tracker on an Altera Arria 10 FPGA using the parallel, cross-platform OpenCL framework. The purpose is to provide a low power solution that also shows accelerated performance. As a result, the Arria 10 FPGA is able to obtain over a 50% decrease in run-time compared to the CPU. The FPGA design was also able to achieve over 30% power efficiency over the GPU implementation and 98% power efficiency over the CPU implementation.
