Abstract:
1. A medical image processing apparatus for detecting a region where a linear structure exists from a piece of image information that is composed of a plurality of pixels and is obtained by picking up an image of a living tissue, the medical image processing apparatus including: a selection portion that selects a pixel of interest from the piece of image information; a first feature value calculation portion that calculates a first feature value of the pixel of interest which is calculated by a first calculation method for extracting a first feature from the plurality of pixels, on the basis of a piece of color tone information of the pixel of interest and pieces of color tone information of surrounding pixels; a second feature value calculation portion that calculates a second feature value of the pixel of interest which is calculated by a second calculation method different from the first calculation method for extracting a second feature different from the first feature from the plurality of pixels, on the basis of the piece of color tone information of the pixel of interest and pieces of color tone information of surrounding pixels; an evaluation value calculation portion that calculates an evaluation value of the pixel of interest serving as a value used to judge on the basis of the first feature value and the second feature value whether the pixel of interest is a pixel corresponding to a linear structure; and an evaluation value judgment portion that judges whether the pixel of interest is a pixel constituting a linear structure, on the basis of the evaluation value calculated by the evaluation value calculation portion.
