Method for automatically scoring excrement picture before colonoscopy detection

Abstract

The invention discloses a method for automatically scoring an excrement picture before colonoscopy detection. The method includes: carrying out gray scale conversion on the standard excrement pictureand the excrement picture to be scored; carrying out sub-region division on the converted gray-scale picture; calculating the spatial average color value of each sub-region and negation; inverting thespatial average color value of each sub-region and storing the inverted spatial average color value in a matrix at a corresponding position; converting the matrix into vectors; drawing a corresponding spatial average color value histogram according to the vector; fitting operation on histograms, obtaining a fitting function and a corresponding fitting vector; calculating the minimum value of thedistance between the fitting vector of the to-be-scored excrement picture and the fitting vector of the standard excrement picture, obtaining the score of the standard excrement picture correspondingto the minimum value of the distance, scoring the to-be-scored excrement picture according to the standard excrement picture. The beneficial effects of being accurate in scoring and facilitating unified evaluation are achieved.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a method for automatically scoring excrement pictures before colonic endoscopy detection. Background technique [0002] Digestive endoscopy is used to diagnose and treat the colon part of the patient, requiring the patient to empty the intestinal tract in advance so that the vision under the endoscope observation is good; in the preparation process before the intestinal examination, the patient does not know his intestinal tract after taking laxatives. The degree of emptying of the tract, and the patient's own judgment on the excrement is not professional, and it is impossible to give an accurate description to the doctor or nurse, which will cause some misleading. Bowel preparation was assessed. Contents of the invention [0003] In order to solve the above problems, the present invention provides a method for automatically scoring excrement pictures before colonosco...
