Abstract
Certain aspects of an apparatus and method for automatic ER/PR scoring of tissue samples may include for determining a cancer diagnosis score comprising identifying a positive stained nucleus in a slide image of the tissue sample, identifying a negative stained nucleus in the slide image, computing a proportion score based on number of the positive stained nucleus identified and number of the negative stained nucleus identified and determining the cancer diagnosis score based on the proportion.

(canceled)
A non-transitory computer-readable storage medium storing one or more computer programs adapted to cause a processor based system to execute steps comprising:
- converting at least a part of image information of a tissue sample to an optical domain image by separating the at least a part of image information into positive stain image information and negative stain image information;
- identifying a number of positive stained nuclei based on the positive stain image information and a number of negative stained nuclei based on the negative stain image information;
- calculating a positive stained nuclei percentage based on a ratio of positive stained nuclei identified based on the positive stain image information to total nuclei included in the at least a part of image information, wherein a percentage score is calculated based on the positive stained nuclei percentage;
- and
- displaying an indication of a cancer diagnosis score derived at least in part from the percentage score.
