The goal is to work in real time under the uncontrolled environment of a sport event like a football match. Since football players are composed for diverse and complex color patterns, a Gaussian Mixture Models (GMM) is applied as segmentation paradigm, in order to analyze sport live images and video. Optimization techniques have also been applied over the C++ implementation using profiling tools focused on high performance. Time consuming tasks were implemented over NVIDIA’s CUDA platform, and later restructured and enhanced, speeding up the whole process significantly. Our resulting code is around 4–11 times faster on a low cost GPU than a highly optimized C++ version on a central processing unit (CPU) over the same data. Real time has been obtained processing until 64 frames per second. An important conclusion derived from our study is the scalability of the application to the number of cores on the GPU. info:eu-repo/semantics/closedAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 1.156 2012 ENGINEERING, ELECTRICAL & ELECTRONIC 117 / 243 = 0.481 2012 Q2 T2 IMAGING SCIENCE & PHOTOGRAPHIC TECHNOLOGY 9 / 23 = 0.391 2012 Q2 T2 COMPUTER SCIENCE, ARTIFICIAL INTELLIGENCE 62 / 115 = 0.539 2012 Q3 T2 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Torres Moreno, Enrique F.
