Abstract
In an embodiment, an imager is used to generate an image of a sample, e.g., a tissue sample including diaminobenzidine tetrahydrochloride (DAB) stained cells. A user selects a region to be scored in the image. A mean intensity value of a selected color is determined from the pixels in the selected region. The selected color may be the complement of a color to be scored, which, in the case of a DAB test, is blue. A score is generated in response to the mean intensity value using a stored calibration curve.
