Parallelization of the Algorithm K-means Applied in Image Segmentation
(International Journal of Computer Applications, 2014-01-01)
Algorithm k-means is useful for grouping operations; however, when is applied to large amounts of data, its computational cost is high. This research propose an optimization of k-means algorithm by using parallelization ...
A novel approach for image feature extraction using HSV model color and niters wavelets
(2013 XXXIX Latin American Computing Conference (CLEI), 2013-11-21)
Due to the advancement of computing and the power of the new hardware, more economical, it is now feasible to have thousands of images which can be analyzed to allow classification for its shape and/or color. Furthermore, ...
