IMAGE PROCESSING DEVICE, IMAGE PROCESSING METHOD, AND IMAGE PROCESSING PROGRAM

摘要

PROBLEM TO BE SOLVED: To detect a contour edge of an object from an object image with accuracy.

SOLUTION: An image processing device 1 of one embodiment of the present invention includes: a gradient strength calculation unit 16 that calculates gradient strength of each pixel based on a pixel value of an intraluminal image imaging mucosal architecture; a candidate edge detection unit 17 that detects contour candidate edge positions based on the gradient strength of each pixel; a reference area setting unit 18 that sets a reference area referred to when a contour edge position is selected from among the contour candidate edge positions based on the gradient strength of each pixel; and a contour edge selection unit 19 that selects one of the contour candidate edge positions in the reference area as the contour edge position.
