Abstract
A digital pathology system receives, via a user interface, a selection of a LOI in a camera view of a PLFP slide under a first optical condition. The PLFP slide is configured to reveal a fiduciary pattern when exposed to a second optical condition that is different from the first optical condition. Responsive to receiving a request, digital pathology system changes optical conditions from the first optical condition to the second optical condition to reveal the fiducial pattern on the PLFP slide, which defines absolute coordinates for the PLFP slide. The digital pathology system determines coordinates for the location of interest based on the revealed fiducial pattern. The digital pathology system displays, in the camera view, the determined coordinates.
