Interpretation method of agglutination test

Abstract

A method for interpreting the agglutination test, which first performs image preprocessing to obtain a digital image of the agglutination test results, and simultaneously processes the brightness and contrast parameters of the image; then uses the "Hough transform" extraction algorithm to analyze the image on a computer vision platform Detect the boundary of the agglutination test area. After extracting the boundary, further extract the boundary according to the color distribution to obtain the histogram of the extracted picture; extract the sample within the boundary of the agglutination test area; extract the sample picture according to the obtained threshold; filter the test The image noise of the sample image is obtained to obtain the sample image; the agglutination reaction spots in the sample image are extracted, and the number and area of ​​the agglutination reaction spots are calculated; finally, the grade of the sample is given based on the obtained number and area of ​​the agglutination reaction spots. The agglutination test interpretation method provided by the present invention uses imaging and computer image processing as means, which greatly improves the reliability of the agglutination test interpretation and reduces the randomness of human eye observation.

Description

technical field [0001] The invention relates to an image data processing method, in particular to a method for processing and distinguishing digital images of agglutination test results, and interpreting and giving test conclusions, so as to realize the automation of agglutination test detection. Background technique [0002] Agglutination test is a serological test in which agglutination occurs after the combination of particulate antigen and corresponding antibody. Under the action of electrolyte, the complex of antigen and antibody forms agglomerated aggregates visible to the naked eye after a certain period of time. The test can be carried out on a glass plate, called the glass plate agglutination test, and the test can be carried out on a card, called the card agglutination test, which can be used for the identification of bacteria and the qualitative detection of antibodies; it can also be carried out in a test tube, called the test tube agglutination test , mainly us...

Problems solved by technology

[0004] The automation level of agglutination test is low. When performing agglutination reaction, manual operation and interpretation are usually performed on a piece of test paper, which increases the labor and time of medical staff
