IMAGE PROCESSING DEVICE AND IMAGE PROCESSING METHOD IN IMAGE PROCESSING DEVICE
First Claim
1. An image processing device comprising:
- an image signal input portion for inputting an image signal on the basis of images obtained by medical equipment having an imaging function;
an image dividing portion for dividing the plurality of images into a plurality of regions, respectively, on the basis of the image signal inputted in the image signal input portion;
a feature value calculation portion for calculating a plurality of types of feature values in each of the plurality of regions divided by the image dividing portion;
a first cluster classifying portion for generating a plurality of clusters in one feature space on the basis of one type of feature value and the occurrence frequency of the one type of feature value in the plurality of types of feature values and for classifying the plurality of clusters into any one of a plurality of classes, respectively;
a second cluster classifying portion for generating a plurality of clusters in another feature space on the basis of another type of feature value and the occurrence frequency of the another type of feature value in the plurality of types of feature values and for classifying the plurality of clusters into any one of the plurality of classes, respectively; and
a cluster division portion for carrying out division processing for the plurality of clusters in the one feature space on the basis of a distribution state of the feature value in the one feature space and the another feature space.

Abstract
A plurality of images inputted in an image signal input portion are divided into a plurality of regions by an image dividing portion, and a feature value in each of the plurality of regions is calculated by a feature value calculation portion and divided into a plurality of subsets by a subset generation portion. On the other hand, a cluster classifying portion classifies a plurality of clusters generated in a feature space into any one of a plurality of classes on the basis of the feature value and occurrence frequency of the feature value. And a classification criterion calculation portion calculates a criterion of classification for classifying images included in one subset on the basis of a distribution state of the feature value in the feature space of each of the images included in the one subset.
