Abstract
A sample profile based on assessment of digitized cell images of noraml, malignant and 2 classes of atypical urothelial cells was established. Data distributed in a multidimensional feature space were projected into a 2-dimensional display space using linear discriminant functions as composite features. Fitting of a polynomial led to the derivation of an atypicality index for each cell and to statistically clearly significant differences in the atypicality values for the 4 groups of urothelial cells.
