Segmentation of White Blood Cell from Acute Lymphoblastic Leukemia Images Using Dual-Threshold Method

Figure 2

Background of dual-threshold method. (a, d) Segmentation results of single-threshold method based on RGB color space or S channel image from HSV color space (only nucleus is extracted). (b) Segmentation result of uniform image using single-threshold method based on H channel image of HSV color space (nucleus and cytoplasm are all extracted). (c) Expected segmentation result of cytoplasm. (e) Segmentation result of image having illumination variations by single-threshold method based on H channel image of HSV color space (much noise exists in segmentation result).
