High structural similarity
WebStructural similarity index When comparing images, the mean squared error (MSE)–while simple to implement–is not highly indicative of perceived similarity. Structural similarity aims to address this shortcoming by taking texture into account [ 1], [ 2]. WebJan 22, 2007 · There is, however, a limit to which structure and sequence similarities may be equivalenced. As has been established in several studies (Kinjo and Nishikawa, 2004; Rost, 1999 ), protein pairs with a sequence identity higher than 35–40% are very likely to be structurally similar.
