Отрывок: The training set was composed of 200 samples of 256×256 pixels, containing 100 images of each class. The images under testing had similar parameters, with the samples containing 100 images in each class. Based on this data, image classification was done. Parallel implementation of the method to generate informative areas The analysis of the algorithm structure showed that the first stage of areas computing has the maximum computa- tional complexity. As mentio...

Аннотация : | This paper proposes a parallel implementation of the image informative segments extraction method. The images are segmented in the spatial spectrum domain. The median energy in each selected segment is viewed upon as an area. For purposes of time savings, a parallel implementation of the algorithm for calculating the areas is developed. The developed approach to the parallel algorithm implementation is tested on a high performance multicore computing system. The experiments have shown that the parallel implementation of the method allows us to obtain a three-fold speedup, which is a good result. |
