Title:
IMAGE PROCESSING DEVICE, IMAGE PROCESSING METHOD, AND IMAGE PROCESSING PROGRAM
Document Type and Number:
WIPO Patent Application WO/2018/220681
Kind Code:
A1
Abstract:
This image processing device is provided with: an alignment amount calculation unit (29) that calculates an alignment amount for corresponding pixels in a standard image and a reference image using a projective transformation matrix; and an image combination unit (31) that combines the standard image with a reference image converted on the basis of the alignment amount. The alignment amount calculation unit (29) comprises: a corresponding region movement amount calculation unit (51) for calculating a movement amount for each of feature regions that correspond between the reference image and the standard image; a clustering processing unit (53) that sorts, into one or more groups, other feature regions except feature regions exhibiting a trend in which the movement amount is different from the movement amount of the other feature regions; and a projective transformation matrix calculation unit (55) that calculates a projective transformation matrix using the movement amounts of the other feature regions.
