Answer 1

White blood cells (WBC) play a significant role in the immune system by protecting the body from infectious disease and foreign invaders. Therefore, an automatic identification of WBC from microscopic images is an essential importance to help the haematologist in diagnosing diseases, such as leukemia, AIDS, and certain types of blood cancer. Analysis of WBC structure from microscopic images and classification of cells into types and sub-types are challenging because of variations in maturation stage, and intra-class variations of the cell shape in images due to using different acquisition and staining processes. Considering the great interest in the community of health, hematology and medical imaging, this chapter reviews a wide range of state-of-the-art approaches in the WBC classification task. Different steps including image aquistion, image enhancement, image segmentation, feature extraction, classification and evaluation will be presented as shown in Fig-1. We first provide an overview of the structure of WBCs, the types and sub-types of WBC, and their features, including the shape of nuclei, size, function and colour.

Red blood cells get their bright red color from a protein that allows them to carry oxygen from your lungs and deliver it to other tissues in your body (hemoglobin). Red blood cells are microscopic and have the shape of a flat disk or doughnut, which is round with an indentation in the center, but it isn't hollow.

Reticulocytes are made in the bone marrow and sent into the bloodstream. About two days after they form, they develop into mature red blood cells. These red blood cells move oxygen from your lungs to every cell in your body. A reticulocyte count (retic count) measures the number of reticulocytes in the blood.
