Embodiment Construction
[0064] In order to verify the feasibility and effectiveness of the present invention, the present invention has done a preliminary simulation and measurement experiment. The experimental blood sample comes from the laboratory department of the hospital. The white blood cell extraction and analysis are completed in the software Matlab2017a, the image size is 1920×1080, and the white blood cell magnification is 4 times; the statistical t-test analysis of the sample parameters is completed by SPSS21.0, such as figure 1 Shown, method described in the present invention comprises:
[0065] 101. Obtain the input original white blood cell image and convert it to a grayscale image. The original image can be recorded as f 0 , the grayscale image can be written as f gray ;
[0066] 102. Convert the grayscale image f gray performing block formation to form image blocks, and randomly extracting the image blocks to be analyzed;
[0067] Optionally, in an embodiment of the present invent...
