Abstract
The detection of bubbles in coverslip adhesive. Bubbles in coverslip adhesive may span large areas of the coverslip. An automated cytology system acquires 4 x gray scale images of the slide. Image conditioning is then performed. The conditioned gray scale image is binomially filtered providing a binomial filtered image. The gray scale image is subtracted from the binomial filtered image to produce a high pass enhanced image. An object mask detection is then performed on the high pass enhanced image. Objects are classified to identify bubble edgest. Multiple detections of bubble edges are pieced together to detect bubbles much larger than the area covered by a single image from the detector and the microscope lens. Bubbles are located even if low level image analysis shows gaps in the edges. The cytological system fills in significant gaps in the detected bubble edges. The result is then used for further processing by the automated cytology system.
