high performance computing on graphics processing units: hgpu.org

In this paper, the authors propose a fast evolutionary image processing system. The authors employ graphics processing unit (GPU) to automatic construction of tree-structural image transformation (ACTIT) for the purpose of reducing optimization time. Besides, the system calculates in parallel by using multiple GPUs for the fast processing. The optimization speed of the proposed system is several hundred times faster than that of the ordinary ACTIT. Experimental results show that the proposed system is effective.
