Claims

[Claims for Utility Model Registration] Based on first image data corresponding to the image density of the first input image,
a first region detecting section that detects a region in an input image; a second area detection unit that detects an area in the input image; and a correspondence that determines the degree of similarity between the area detected by the first area detection unit and the area detected by the second area detection unit. a first band that outputs a first bandpass filter output according to a frequency of density change of the first input image based on the first image data; a pass filter output processing section; a second band pass filter output processing section that outputs a second band pass filter output according to the frequency of density change of the second input image based on the second image data; and the association processing unit: associates the image density of the first input image and the output of the first bandpass filter with the image density of the second input image and the output of the second bandpass filter. An image matching device comprising: a comparison means for making a comparison; and a similarity detection means for determining the degree of similarity based on the comparison result of the comparison means.
