Abstract
An image processing apparatus includes: a model estimator that models gradient variations of pixel values in an image of a captured object, which is an in-vivo image, according to the pixel values in the image; and an abnormality candidate detector that detects an abnormality candidate area on the object shown in the image according to a difference between a pixel value of each pixel constituting the image and an estimated pixel value of each pixel, the estimated pixel value being determined according to the modeled gradient variations of the pixel values.
Claims23
An image processing apparatus comprising:
- a model estimator that models gradient variations of pixel values in an image of a captured object, which is an in-vivo image, according to the pixel values in the image;
- and
- an abnormality candidate detector that detects an abnormality candidate area on the object shown in the image according to a difference between a pixel value of each pixel constituting the image and an estimated pixel value of each pixel, the estimated pixel value being determined according to the modeled gradient variations of the pixel values.
An image processing program recording device having stored thereon an image processing program that causes a computer to perform:
- a model estimating procedure that models gradient variations of pixel values in an image of a captured object, which is an in-vivo image, according to the pixel values in the image;
- and
- an abnormality candidate detecting procedure that detects an abnormality candidate area on the object shown in the image according to a difference between a pixel value of each pixel constituting the image and an estimated pixel value of each pixel, the estimated pixel value being determined according to the modeled gradient variations of the pixel values.
An image processing method comprising:
- a model estimating step that models gradient variations of pixel values in an image of a captured object, which is an in-vivo image, according to the pixel values in the image;
- and
- an abnormality candidate detecting step that detects an abnormality candidate area on the object shown in the image according to a difference between a pixel value of each pixel constituting the image and an estimated pixel value of each pixel, the estimated pixel value being determined according to the modeled gradient variations of the pixel values.
