Abstract

The Pytiev morphological shape comparison technique is extended for Serra mathematical morphology. Instead of a constant set of connected regions with variable intensity, a constant morphological skeleton with a variable radial (scale) function is applied as an image shape descriptor. This allows projecting binary patterns onto shapes of other patterns and calculating the respective morphological correlation coefficients.
