In this paper, we present an improved Jensen-Shannon divergence (JSD) based spatiogram similarity measure. The spatial-color joint probability distribution of the pixels corresponding to each bin is regarded as a weighted Gaussian distribution. Then, the similarity of corresponding bin of two spatio...
Jensen Jensen-Shannon Divergence (JSD)是Kullback-Leibler divergence(KLD)的一个变种,转换方式如下: JSD(P||Q) = 1/2*(D(P||M)+D(Q||M)) JSD(P∥Q)=12D(P∥M)+12D(Q∥M)JSD(P∥Q)=12D(P∥M)+12D(Q∥M) M=1/2*(P+Q) 参考:http://en./wiki/Jensen%E2%80%93Shannon_divergence D...
