<p>The present invention describes an apparatus and technique for finding spots in an image with substantial noise making it difficult to identify without specialized noise suppression algorithms. The image analysis technique described applies the tolls of mathematical morphology and prior information about the shape of illumination patterns to remove noise and isolate the points of interest for further mathematical analysis. The apparatus (10) includes a light source (12), a disk plate (14) having a pattern of holes, a non-distorting beam-splitter (16), a lens (18) which projects an image of target (14) onto an image plane (22) which is close to or coincidental with objective lens (20).</p> |
