Comparison for partial and dark contrast stretching on abnormal bone marrow slide images for leukemia screening

Abstract

Image enhancement is often carried out on medical images to improve the quality of the images for further analysis that needs to be done afterwards. It is the most fundamental digital image processing approach done on the bone marrow slide images. Bone marrow slide images are needed to be enhanced in terms of its contrast, brightness and clarity to eased the leukemia screening process. Image enhancement technique is done on the images entirely which includes the White Blood Cells (WBCs), Red Blood Cells (RBCs) and Background (BG). This paper will present the implementation of two image enhancement techniques which are the Partial Contrast Stretching (PCS) and Dark Contrast Stretching (DCS) on bone marrow slide images. Both techniques show good results despite of its slight difference in algorithm.
