Abstract:
1. An image processing apparatus comprising: an image acquiring unit that acquires an in-vivo image being a captured image of an inside of a body cavity; a processor; and a memory storing computer readable instructions that, when executed by the processor, implement: a feature-data calculating unit that calculates feature data corresponding to a pixel or an area in the in-vivo image; a body-tissue extracting unit that extracts, as a body tissue, a pixel or an area whose feature data corresponds to a predetermined threshold; a criterion creating unit that creates a criterion for detecting a detecting object based on the feature data of the body tissue; a detecting unit that detects a body tissue corresponding to the criterion as the detecting object; and a distribution forming unit that obtains a feature-data distribution of the body tissue based on the feature data, wherein the criterion creating unit creates the criterion based on the feature-data distribution of the body tissue and a known property of the feature data of the detecting object; wherein the criterion is a determination threshold in a feature space, and the criterion creating unit sets a determination threshold at a location closer to a location of the feature-data distribution of the body tissue in the feature space as the location of the feature-data distribution of the body tissue comes closer to the known property of the feature data of the detecting object.
