Paper Abstract

In threshold decomposition image processing an input grayscale image is decomposed into a sequence of binary slices, each corresponding to a different threshold value. Each slice is processed in some way and the results added. In an optoelectronic system the processing operation often involves a spatial filtering operation, and most likely followed by a nonlinearity. Ranked-order filtering of grayscale images can be performed with digital accuracy. Relatively simple optoelectronic implementation of threshold-dependent processing is also possible. Texture segmentation can be performed independent of illumination level.
