Problems solved by technology

[0006] However, when only applying the above-mentioned dynamic contour extraction method to extract the closed area, the closed area extracted by how to define the initial position and each energy value of the closed area is quite different.
Therefore, closed regions may not be properly extracted, and as a result, abnormal parts may be detected for groove positions or outline parts, and they may be misdetected.

Abstract

Provided is an image processing apparatus and an image processing method. The apparatus includes a calculating unit that calculates gradient strength of respective pixel values based on an intraluminal image, an extracting unit that extracts a closed region from the image, and a detecting unit that detects an abnormal portion of the closed region. The closed region satisfies conditions that the pixel of which gradient strength is a predetermined value or more is not included in the closed region and a boundary of the closed region does not bend with predetermined curvature or higher toward an inner side of the closed region. The extracting unit includes a setting unit that sets an initial closed region based on the gradient strength, an energy calculating unit that calculates values of types of energies based on an outer shape of the closed region and the gradient strength, and an energy weighted-sum calculating unit that calculates a weighted sum of the types of energy.

Description

technical field [0001] The present invention relates to an image processing device and an image processing method for processing an image of a lumen in a living body obtained by photographing a lumen in a living body. Background technique [0002] Conventionally, endoscopes have been widely used as medical observation devices that are introduced into the body of a subject such as a patient to observe the inside of a lumen inside the body. In addition, in recent years, an ingestion-type endoscope (capsule endoscope) having an imaging device inside a capsule casing and a communication device for wirelessly transmitting image data captured by the imaging device outside the body has been developed. Observing and diagnosing images of internal lumens (in vivo lumen images) captured by these medical observation devices requires a lot of experience, so it is desirable to have a medical diagnosis support function that assists doctors in diagnosis. As one of the image recognition tec...
