1. In an automated system for analyzing a biological specimen having a thick group of cells, a thick group of cells classification apparatus comprising:

  • (a) an automated microscope having at least one image output;

    (b) image segmentation means for identifying objects of interest connected to the image output, wherein the image segmentation means has a segmented image output;

    (c) object feature calculation means for measuring properties of each segmented object having a segmented object output wherein the object feature calculation means has a thick group of cells object feature output; and

    (d) an object classification means for classifying thick group objects for analysis having an input connected to the thick group of cells object feature output, where the object classification means has a thick group of cells classification output, and where the object classification means comprises a multiple stage algorithmic classifier, wherein every stage is an algorithmic classifier and wherein at least one of the stages comprises a Fisher'"'"'s binary decision tree classifier.
