Multicore DSP implementation of adaptive correlation tracker

This paper presents multicore implementation of an adaptive correlation tracking technique to track aerial target. The principle novelty of the proposed algorithm is its adaptiveness to changes in target size, illumination and target occlusion, etc during tracking. Tracking window size is adjusted according to the target size and tracking window is displaced depending on the tracking error generated during the course of tracking. Tracking correctness is achieved by estimating a confidence value for updating the template imagery periodically. During occlusion, target future positions are predicted by applying inverse exponential based prediction algorithm. The proposed tracking scheme is implemented on multi-DSP platform and fast tracking is accomplished at a rate of 100 frames / sec on image size of 640 times 512 pixel resolutions.
