Bhagya, M.Tripathi, S.Santhi Thilagam, P.S.2026-02-0620032014 14th International Conference on Hybrid Intelligent Systems, HIS 2014, 2003, Vol., , p. 135-140https://doi.org/10.1109/HIS.2014.7086186https://idr.nitk.ac.in/handle/123456789/33424This paper presents a technique to optimize contour based template matching by using General Purpose computation on Graphics Processing Units (GPGPU). Contour based template matching requires edge detection and searching for presence of a template in an entire image, real time implementation of which is not trivial. Using the proposed solution, we could achieve an implementation fast enough to process a standard video (640 × 480) in real time with sufficient accuracy. © 2014 IEEE.computer visionimage edge detectionimage recognitionimage sampling
