Before revision:  At some point in an image, the color perceptually seems more similar to that of the adjacent locations , while being more dissimilar from that of remote neighbors. The influence of neighbors hence reverses its nature above some characteristic scale .
After revision:  At some point in an image, the color perceptually seems more similar to that of the adjacent locations , while being more dissimilar from that of remote ones. Thus, their combined effects are enhanced in the presence of a spatial pattern, and can be measured as larger shifts in color matching experiments .
