Han Yu-la · Journal of Guangxi University for Nationalities · 2015
In order to reduce the computation time an accelerated algorithm which based on the efficient Summed Square Image(SSI)scheme is proposed in this paper.The new algorithm uses Gaussian filter to do the coarse denoising for original image first,and then SSI scheme is introduced to calculate the similarity of block.Besides,in the second process of BM3 Dwhich called wiener filtering,integral image can also be applied after the corresponding conversion of the original algorithm.Experiments have shown that the proposed algorithm not only retains the superior performance of BM3 Dalgorithm,but also reduces the operation time by about 3times.
