Embodiment Construction
[0048] Below in conjunction with accompanying drawing, the automatic detection process of leukocyte in a kind of bronchoalveolar lavage smear of the present invention is described in detail:
[0049] Step 1: Use a microscope to collect microscopic images of the bronchoalveolar lavage smear;
[0050] Step 2: Grayscale the image in step 1 and convert it into a grayscale image;
[0051] Step 3: convert the grayscale image in step 2 into a binarized image;
[0052] Step 3-1: Set the gray threshold in the binarization process to be the gray threshold obtained by using the maximum inter-class variance method for the gray image;
[0053] Step 3-2: Compare the grayscale value of each pixel in the grayscale image with the grayscale threshold. If it is greater than the grayscale threshold, the grayscale of this point is set to 0. If it is smaller than the grayscale threshold, the grayscale of this point is set to 0. The degree is set to 255 to obtain a binary image;
[0054] Step 4: ...
