Claim Text:
1. A method for relocating an object of interest at a second imaging station based on coordinates for the object of interest at a first imaging station, the method comprising: acquiring a first pair of images including a reference image of a specimen on the first imaging station and a second image of the specimen on the second imaging station, the reference image being selected from a plurality of reference image candidates based on a suitability score assigned to the reference image candidates, wherein the suitability score for a particular reference image candidate is assigned based on identifying, in the particular reference image candidate, areas where a number of cells is lower than a threshold; identifying a cell group that appears in both the reference image and second image; determining stage coordinates of the cell group on the first imaging station from stage coordinates at which the reference image was acquired; determining stage coordinates of the cell group on the second imaging station from stage coordinates at which the second image was acquired; and calculating an affine transformation that converts the stage coordinates of the first imaging station to the stage coordinates of the second imaging station.
