    Abstract: A body part point detection module detects multiple first body part points associated with a first person image contained in a first image and multiple second body part points associated with second person images contained in a second image. An identicality determination module calculates color differences between the color information of the pixels corresponding to the multiple first body part points of the first person image and the respective color information of the pixels corresponding to the multiple second body part points of the second person images, and uses the calculated color differences to calculate the degree of color similarity between the first person image and second person image and the degree of color similarity between the first person image and second person image. The identicality determination module uses the calculated degrees of color similarity to determine identicality between the first person image and second person images.
