The optimization of image processing using GPU
The approaches to optimize image processing on GPU on the example of the median filtering algorithm are described in the paper. A comparison is performed with free CPU image processing library, using AVX2 vector instructions. The reached filtration rate of 100 GPixels/sec on 3×3 square on Titan Pascal GPU and the specific filtration rate of 10.2 GPixels/sec per 1 TFlops on 3×3 square for single accuracy are highest from known ones in the world at present.
