We propose a dual-threshold method based on strategic combination of RGB and HSV color space for white blood cell (WBC) segmentation. The proposed consists three main parts: preprocessing, threshold segmentation, postprocessing. In the preprocessing part, we get two images further processing: one contrast-stretched gray image H component from transformed space. segmentation is improving conventional single-threshold approaches golden section search used determining optimal thresholds.
