A method for high speed morphological processing in a computerized image processing system starts by acquiring a binary image and selecting feature and height values corresponding to a desired morphological processing of an image. The image is scanned in a raster scanning sequence so as to produce a scanned image including a plurality of pixels. A sequential labeling transformation is performed on each of the plurality of pixels of the scanned image so as to produce a transformed image. A thresholding operation is performed on the transformed image. The resultant image is translated.
