Claim 6:
7. A method of identifying candidate target cells within a biological fluid specimen, the method comprising:
receiving a digital image of the biological fluid specimen;
identifying one or more candidate regions of pixels in the digital image by identifying connected regions of pixels of a minimum intensity having a size between a minimum size and a maximum size and an aspect ratio that meets a threshold; and
for each candidate region of at least one of the one or more candidate region
analyzing the image to identify distinct gray levels in the candidate region,
performing a count of the gray levels, and
determining that the count of gray levels is more than a threshold number of intensity levels, and responsive to determining that the count of gray levels is more than the threshold number, continuing to treat the portion of the image as a candidate for classification.
