Bhagya, M.Tripathi, S.Santhi Thilagam, P.2026-02-052015International Journal of Computer Information Systems and Industrial Management Applications, 2015, 7, 1, pp. 32-40https://idr.nitk.ac.in/handle/123456789/26364This 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 (640x480) in real time with sufficient accuracy.Computer visionImage edge detectionImage recognitionImage sampling
