An image processing apparatus includes a feature value calculating section that calculates a feature value from an image picked up of a living mucous membrane, an extraction section that extracts a structure corresponding to the feature value, and a region division section that divides the structure into partial regions according to a predetermined condition.

Image processing apparatus and method of operation of image processing appartus

A medical image processing device includes an input section to which a biological mucous membrane image obtained by picking up an image of a biological mucous membrane is inputted, a region extracting section that extracts a mucous membrane microstructure region corresponding to a mucous membrane microstructure from the inputted biological mucous membrane image, a closed region identifying section that identifies at least one closed region regarded as being surrounded by the mucous membrane microstructure region, and a unit region setting section that sets a biologically histological unit region on the basis of the mucous membrane microstructure region and the closed region.

Medical image processing device

An image processing apparatus includes: a basic shape matching section that extracts, as a structure region, a predetermined structural object included in an image obtained by picking up an image of a mucosal surface of a living body, and matches each of regions resulting from the structure region being divided, the regions each including at least one pixel, with a first region having a first basic shape or a second region having a second basic shape; a feature value calculating section that sequentially sets regions of interest from among the regions matched by the basic shape matching section, and calculates counts of the first regions and the second regions adjacent to each of the regions of interest; and a classification section that classifies the structure region based on a result of the calculation by the feature value calculating section.

Image processing apparatus and image processing method

An image processing apparatus includes: an image input section via which a medical image picked up of a mucous surface of a living body is inputted; a setting section that sets a region of interest as a first region and a second region including a unit region in the medical image; a feature value calculating section that calculates a first feature value relating to a shape of the region of interest based on pixel values of the region of interest and a region in a periphery thereof and a second feature value relating to a shape of the unit region based on pixel values of the unit region and a region in a periphery thereof; and an matching section that matches the region of interest with a predetermined shape based on distributions of the first feature value and the second feature value calculated by the feature value calculating section.

Image processing apparatus

An image processing apparatus of the invention includes a first feature value calculation unit adapted to calculate a first feature value for each pixel in an image picked up of living tissue, where the first feature value represents a value of an index which indicates what shape a local region; a second feature value calculation unit adapted to calculate a degree of concentration of a gradient vector as a second feature value based on the gradient vector for each pixel in the image; an evaluation value calculation unit adapted to calculate a geometric evaluation value for each pixel, based on calculation results of the first feature value and the second feature value; and a region extraction unit of separately extracting a candidate region of the linear structure and a candidate region of the massive structure based on a calculation result of the geometric evaluation value.
