AI Technical Summary

Problems solved by technology

The existing automatic counting method usually needs to add a hemolytic agent, and the red blood cell fragments will affect the white blood cell count and classification results, resulting in the presence of obvious side peaks on the left side of the white blood cell histogram, resulting in inaccurate results

Embodiment Construction

[0061] The present invention can be better understood from the following examples. However, those skilled in the art will readily understand that the specific material ratios, process conditions and results described in the examples are only used to illustrate the present invention, and should not and will not limit the present invention described in detail in the claims .

[0062] White blood cell automatic identification and counting methods, such as figure 1 shown, including the following steps:

[0063] Step 101, enlarge the blood smear to an appropriate ratio under the microscope, and convert the microscopic cell image into a digital cell image by using a scanning microdensitometer or a TV camera and inputting it into a computer;

[0064] Step 102, preprocessing the input image;

[0065] Step 103, performing color space conversion;

[0066] Step 104, then using the grayscale image segmentation method based on boundary support vectors to segment white blood cells from ...

Abstract

The invention provides a method for automatically identifying and counting white blood cells. The method comprises the following steps of: preprocessing, color space conversion, coarse segmentation, checking of white blood cells, fine segmentation, characteristic parameter extraction, identification and classification, result output and the like. The method can be used for automatically identifying and classifying the white blood cells in blood by extracting a group of cell characteristic parameters and utilizing a support vector machine, and has the advantages of high classification efficiency, good effect, high accuracy, high stability and high robustness.

Description

technical field [0001] The invention belongs to the white blood cell analyzer in the technical field of medical equipment, and in particular relates to a white blood cell automatic identification and counting method. Background technique [0002] Blood cells are roughly divided into three categories: red blood cells, white blood cells, and platelets, among which white blood cells are composed of lymphocytes, monocytes, neutrophils (subdivided into neutrophil rod-shaped granulocytes and neutrophil segmented granulocytes), There are five subtypes of eosinophils and basophils. In the field of biological analysis, especially in the field of clinical test analysis, accurate classification of different subtypes of leukocytes plays a very important role in diagnosis and research, and the changes in the content of each subtype of leukocytes are used clinically as an indicator of diagnosis and treatment. Important indicators. For example, acute bacterial infection can cause neutrop...
