ABSTRACT:
A method and apparatus for analyzing an illuminated subject. In the preferred embodiment, the subject is a stained blood smear. A first signal is produced which represents a first predetermined wavelength band of the subject modified illumination at a region in the subject. A second signal is produced which represents a second predetermined wavelength band of the subject modified illumination at the region. The two wavelength bands are selected to produce differential contrast between at least two different regions in the subject. The two signals are algebraically combined with thresholding to classify the subject regions in at least one of a predetermined number of categories. Further, signal processing is employed to compile partial and complete features for a predetermined region or cell.
