Morphology
Version 3.0 adds a broad suite of new mathematical morphology tools open up
broad new classes of applications in segmentation and image enhancement.
The existing dilation and erosion operators have been extended to work with
grayscale images. New functions range from additional basic operators
(opening, closing, tophat) to advanced tools useful for segmentation (distance
transforms, reconstruction-based operators, and the watershed transform).
The functions use advanced techniques for high performance, including
automatic-structuring element decomposition, 32-bit binary image packing,
and queue-based algorithms.
