1. A bubble mapper apparatus comprising: (a) imaging means for capturing an image of a slide to obtain a representation of the image; (b) means for detecting bubble edges from images to generate a bubble edge output; (c) dilation means for dilating the bubble edge output to generate a dilated bubble edge map; (d) means for connected component analysis on the dilated bubble edge map to produce a labeled bubble map; (e) means for horizontal and vertical filling the labeled bubble map to produce a binary bubble map; and (f) erosion means for eroding the binary bubble map to produce a final bubble map.
