Abstract
An image identifying device includes a mechanism that sets an evaluation area whose category is to be identified in an in-vivo image; a mechanism that acquires texture components from the evaluation area in the in-vivo image; a mechanism that calculates an evaluation value indicating homogeneity of the texture components; and a mechanism that identifies the category of the evaluation area on the basis of the evaluation value.
Claims18
An image processing device comprising:
- a processor;
- and
- a memory storing computer-readable instructions that, when executed by the processor, implement:
- an evaluation area setting unit that sets an evaluation area whose category is to be identified in an in-vivo image;
- a texture component acquiring unit that acquires texture components from the evaluation area in the in-vivo image by eliminating structural components from the evaluation area in the in-vivo image;
- an evaluation value calculating unit that calculates an evaluation value indicating homogeneity of the texture components;
- and
- an identifying unit that identifies the category of the evaluation area on the basis of the evaluation value;
- wherein the evaluation value calculating unit includes a biased-evaluation-value calculating unit that calculates an evaluation value indicating homogeneity of texture components in a coordinate space, and
- the in-vivo image is an intra-gastrointestinal image.
An image processing method comprising:
