The Problem
MotivationThe classification systems require segmentation: local adaptivesegmentation, seed growing, mathematical morphology, Hough transformadn active contours.
Cost: computational and economic development. Jantzen and Douniaspropose several cell features.

Classification Models
KNN: is a intuitive methos tha classifies unlabeled samplesbased on theri similarity whit samples in the training set.
SVM: is a classification model that finds an optimalseparating hyperplane that discriminates two classes.
