Image processing apparatus and non-transitory computer readable medium for obtaining similarity between a local color displacement distribution and an extracted color displacement

摘要

An image processing apparatus includes a color displacement calculation unit, a distribution obtaining unit, and a similarity calculation unit. The color displacement calculation unit calculates local color displacements that are color displacements locally occurring in individual regions of interest of a given image. The distribution obtaining unit obtains distribution of the local color displacements with respect to an extracted-color displacement that is a displacement of a color preset in a reference region set for the regions of interest. The similarity calculation unit calculates similarity to the extracted-color displacement for the regions of interest using the distribution.
