Abstract
A method for refining virtually-stained image annotations. The method includes separating an image of a stained tissue section into an image of a counterstain and an image of immunostaining visual signals via linear transformation. The method includes identifying and segmenting nuclei in the image of the counterstain to produce an image of a refined counterstain with single-cell segments. The method includes comparing immunostaining visual signals in the single-cell segments of the image of the refined counterstain to a user-defined threshold to determine true positive cells. The method includes refining the image of the immunostaining visual signals to produce an image of refined immunostaining visual signals. The refining is based on the stained tissue section protein localization or morphology and the determined true positive cells. The method includes overlaying the image of the counterstain and the image of refined immunostaining visual signals to produce a refined virtually-stained image annotation.
