Enhancing Blood Cell Images using Denoising Filters for the Detection of Hematological Disorders.

Hematological disorders refer to the diseases caused with the changes in blood cells or blood system such as Leukemia, Anemia, Malaria and Azotemia. Preprocessing of blood cell images is very important step in the detection of these disorders. Hence after image acquis ion from hematologists and oncologists denoising and edge detection are to be done to enhance the image for segmentation of blood cell images and leukocytes, erythrocytes and thrombocytes. Because leukemia can be detected from leukocytes and malarial parasites can be detected from erythrocytes. In this paper we have applied few techniques such as Gabor filter, Gaussian filter, Prewitt filter, Sobel and Canny edge operators for the preprocessing purpose. We have compared the performance of these techniques based on their accuracy and resolution. [ABSTRACT FROM AUTHOR]
