Problems solved by technology

[0003] However, there is such a problem that the image of the inside of the lumen will contain areas whose brightness values ​​do not correspond to the three-dimensional shape
Therefore, when processing such an intraluminal image including a region that does not correspond to the three-dimensional shape, pixels corresponding to the three-dimensional shape of the subject may not be properly acquired even if the above-mentioned Japanese Patent Application Laid-Open No. 2007-236629 is applied, for example. value
And, as a result, the shape may not be accurately estimated in the later stage of processing

Abstract

The invention provides an image processing device and an image processing method. This image processing device includes an area extracting unit that analyzes the internal pixel value and the three-dimensional shape of the object to be captured based on the pixel value of the image inside the lumen obtained by imaging the inside of the lumen or information on the change in pixel value with respect to surrounding pixels. Extracting the candidate area of ​​the non-corresponding classification object area; sort.

Description

technical field [0001] The present invention relates to an image processing device and an image processing method for processing an image of the inside of a lumen obtained by photographing the inside of a lumen. Background technique [0002] Japanese Patent Application Laid-Open No. 2007-236629 discloses a method of estimating the three-dimensional shape of living tissue from an image inside a lumen (endoscopic image), and based on shape feature quantities such as curvature at each position of the inferred three-dimensional shape. , to detect polyps and other lesions with raised shapes. Here, when estimating the three-dimensional shape, it is necessary to obtain pixel values ​​corresponding to the three-dimensional shape of the subject from the image inside the lumen. The three-dimensional shape is estimated by performing a conversion process based on the geometry of the pixel value corresponding to the pixel value of the three-dimensional shape. [0003] However, there is...
