At this stage, white blood cells are extracted as a separate image, and exam help red blood cells have varying intensities; hence, it is greatest to develop separate preprocessing steps for each cell type. Figure 2 shows exam help overall preprocessing steps for WBCs. To remove RBCs from exam help image, exam help RGB image was converted into grayscale image by casting off exam help Hue and saturation data while maintaining its luminance, as shown in Figure 3b, after which converted exam help image to binary using thresholding using a threshold value 64; visualize exam help WBCs, as shown in Figure 3c. Some undesired holes gave the impression in exam help cells, and exam help morphology operator, fill holes were used to remove them. The complementary images before exam help holes were filled, as shown in Figure 3d. This image eroded to minimize exam help number examination help overlapping cells, as shown in Figure 4a.
