A parallel implementation of TLD algorithm using CUDA

Visual tracking is an important issue of computer vision, TLD is an on-line visual tracking algorithm with good robustness and high accuracy properties. However, the real-time performance of TLD is low for the large size video sequences. In this paper, we study the most time-consuming stages of TLD, and then propose a parallel algorithm based on CUDA. The experimental results show that the speedup of our algorithm reaches up to 2.59 compared to TLD while maintaining the same detection accuracy.
