Image processing apparatus, image processing method, and computer-readable recording device

摘要

An image processing apparatus includes an abnormal portion candidate region detection unit configured to detect a candidate region of an abnormal portion based on color information of each pixel constituting an image obtained by capturing an image of an inside of a lumen of a subject, a border neighboring pixel identifying unit configured to identify a border neighboring pixel which is a pixel existing in proximity to a border of the candidate region, a feature data calculation unit configured to calculate feature data based on a pixel value of the border neighboring pixel, and an abnormal portion region distinguishing unit configured to distinguish an abnormal portion region based on the feature data.

主权项

1. An image processing apparatus comprising:
a processor comprising hardware, wherein the processor is configured to:
detect a plurality of candidate regions of abnormal portions based on color information of each pixel constituting an image obtained by capturing an image of an inside of a lumen of a subject;identify a border neighboring pixel which is a pixel existing in proximity to a border of each of the plurality of candidate regions;calculate feature data based on a pixel value of the border neighboring pixel; anddistinguish an abnormal portion region based on the feature data,wherein the processor, in identifying the border neighboring pixel, is configured to limit a border used for identifying the border neighboring pixel, to a part of an entire periphery of the border, andwherein the processor, in limiting the border, is configured to:
identify, for each of the plurality of candidate regions, an effective pixel which is a pixel in a region effective for calculation of the feature data, from an external side region which is in a specified range outwardly from a border pixel located at the border of each of the plurality of candidate regions; andset a border corresponding to the effective pixel.
