IMAGE PROCESSING APPARATUS, IMAGE PROCESSING METHOD, AND IMAGE PROCESSING PROGRAM

摘要

PROBLEM TO BE SOLVED: To accurately detect an abnormal portion from an intraluminal image.

SOLUTION: In the image processing apparatus 1, a closed region extracting part 22 includes: an initial closed region setting part 23 for setting an initial shape of a closed region; an energy calculating part 24 for calculating values of a plurality of types of energy at least including the energy determined by the contour of the closed region and the energy determined by the gradient strength in the boundary of the closed region; an energy weighted-sum calculating part 27 for calculating a weighted sum of the values of the plurality of types of energy; an update range determining part 29 for determining an update range for updating the shape of the closed region based on the value of one of the plurality of types of energy; and a closed region updating part 28 for updating the shape of the closed region within the update range.
