Paper Abstract

Morphological shape transformations on binary imagery can be performed by optically convolving the input image with the desired structuring element (e.g., a disk) and thresholding the output. Photographic film can be used for thresholding, but better results are obtained with electronic scanning and hard-limiting. Erosions, dilations, and median filtering can be performed directly. Openings and closings require an image store and feedback. Results of simple experiments are presented.
