IMAGE PROCESSING APPARATUS, IMAGE PROCESSING METHOD AND IMAGE PROCESSING PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide an image processing apparatus or the like capable of accurately determining a normal visible blood vessel having a color feature amount similar to an abnormal region such as flare and blood point.SOLUTION: An image processing apparatus for processing an image acquired by imaging an organism comprises: a blood vessel candidate region extraction unit 110 which extracts a plurality of blood vessel candidate regions from the image; an identical blood vessel candidate region extraction unit 120 which extracts a blood vessel candidate region group estimated to be a line shape when integrated as an identical blood vessel candidate region among the plurality of blood vessel candidate regions; an evaluation value calculation unit 130 which calculates one or more kinds of evaluation values for evaluating identical blood vessel likelihood with respect to the identical blood vessel candidate region; and a blood vessel region determination unit 140 which determines whether or not the identical blood vessel candidate region forms an identical blood vessel region on the basis of the evaluation value.
