Embodiment Construction
[0032] The present invention will be described in further detail below in conjunction with specific embodiments.
[0033] A leukocyte image segmentation method, comprising the steps of:
[0034] (1) Initial region of interest (ROI) extraction:
[0035] ① Take the green component image of the color image of stained white blood cells as the input image.
[0036] ②Reduce the resolution of the input image.
[0037] The resolution reduction factor dRate depends on the median cellSize of the length and width of the smallest cell in the image. In this example, dRate=Round(cellSize / 10), and Round() is a rounding function.
[0038] ③Statistically reduce the histogram of the input image after resolution reduction.
[0039] ④ Obtain the gray level Hmax of the nth pixel of the histogram;
[0040] n=pRate×(input image length / dRate)×(input image width / dRate), pRate is the ratio of cell pixels to the entire input image pixels, which can be obtained from prior knowledge.
[0041] ⑤ Find ...
