Abstract

The invention discloses a method for detecting in-vivo chromaticity abnormality. The method comprises the following steps: 1, converting an image to an HSV color space and an RGB color space, extracting spectral characteristics of the image from the HSV color space and the RGB color space, and screening pixel points of which spectral characteristics meet preset conditions, wherein the pixel points are primarily-screened pixel points; 2, by using a BP neural network mathematical model, secondarily screening the primarily-screened pixel points to obtain pixel points with abnormal chromaticity, wherein the pixel points are abnormal pixel points; 3, forming abnormal blocks by the abnormal pixel points in continuous distribution in the image, acquiring the number of the abnormal pixel points in each abnormal block, defining the abnormal block with the maximum number of the abnormal pixel points as the maximum abnormal block, comparing the maximum abnormal block with a preset threshold of an abnormal-chromaticity image, and according to the preset threshold, judging whether the image is the abnormal-chromaticity image or a normal-chromaticity image. By the method, the abnormal blocks can be accurately and rapidly judged.

Description

technical field [0001] The invention relates to the field of medicine and medical treatment, in particular to a method for detecting abnormal chromaticity in a living body. Background technique [0002] Gastrointestinal diseases mostly cause changes in the chromaticity or structure of the gastrointestinal mucosa. Abnormal chromaticity of the gastrointestinal mucosa may be caused by bleeding, and bleeding can be caused by inflammation, ulcers, mechanical injuries, vascular lesions, tumors and other factors in the gastrointestinal tract itself. , It can also be caused by lesions of adjacent organs and systemic diseases involving the digestive tract. Currently known methods for detecting bleeding include endoscopy, angiography, barium X-ray examination, and radionuclide imaging. The diagnosis of the site is somewhat difficult. In view of the above problems, the present invention provides a method for detecting abnormal chromaticity in vivo, which is used to detect abnormal ch...
