Compound Regulated Morphological Operations and Their Application to the Analysis of Line-Drawings

Regulated morphological operations, which are defined by extending the fitting interpretation of the ordinary morphological operations, have been shown to be less sensitive to noise and small intrusions or protrusions on the boundary of shapes. The compound regulated morphological operations, as defined in this paper, extend the fitting interpretation of the ordinary compound morphological operations. Consequently, these regulated morphological operations enhance the ability of the ordinary morphological operations to quantify geometrical structure in signals in a way that agrees with human perception. The properties of the compound regulated morphological operations are described, and they are shown to be idempotent, thus manifesting their ability to filter basic characteristics of the input signal. The paper concludes with some examples of applications of compound regulated morphological operations for the analysis of line-drawings.
