The invention relates to a method for segmentation of dyed leukocytes in blo od smears, whereby the pixel of the digital image taken of the blood smear is allocated to one of at least three pixel classes according to the colour val ue thereof, the colour values of all pixels of the image are subjected to the same transformation by means of which the class of pixel allocated to the image background appears white, a transformation of the obtained colour imag e into an alternative colour space is carried out, representing colour tone, colour saturation and colour intensity separately, colour tone, colour saturation and colour intensity are determined for each pixel, the probabili ty value for each pixel that said pixel belongs to a leukocyte is calculated, said probability value being the product (Pwbc) of the probability value (Pnnc) for the leukocyte nucleus colour tone with at least one further probability value, said probability values being fixed by means of previousl y determined and fixed relationships and pixels with a high value for the product of probability values are considered to belong to a leukocyte.</SDOA B> |
