Abstract
A decaying, propagating reference signal allows for the efficient implementation of various image morphological operations, including grayscale dilations and erosions, with only two passes through the image. Pyramid and other morphological shape operators can be duplicated by varying the decay rate(s) of the reference signal, the offset directions and magnitudes of the comparison vector(s), and the paths and number of passes through the image. The methods may also be performed in parallel on the same input image to generate an adaptive threshold image defined as the biased average of an image separately transformed by a dilation and by an erosion. Applications of the technique in one and two dimensions are disclosed.
