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

摘要

PROBLEM TO BE SOLVED: To provide an image processing device or the like that can highly accurately discriminate between a mucosal region and a non-mucosal region such as residue included in an intraluminal image.

SOLUTION: The image processing device is provided which discriminates between a mucosal region and a non-mucosal region included in an intraluminal image, the image processing device includes: a residue candidate region detecting unit 16 that detects a residue candidate region to be discriminated whether it is a mucosal region or not, on the basis of a feature amount of each pixel constituting the intraluminal image; a structure edge region detecting unit 17 that detects a structure edge included in the intraluminal image; and an approximate structure edge line calculating unit 18 and an overlap determining unit 19 that discriminate whether the residue candidate region is a mucosal region or not, on the basis of a relative positional relationship between the structure edge and the residue candidate region.
