Image analysis using select-only morphological operators
Yury V. Visilter · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 2000
This paper describes a new selective morphology (SM) that provides the morphological operators with selecting-only and filtering-only properties (S-operators and F-operators). In this framework, S-opening and S-closing operators perform the extreme monotonous reconstruction of source image, starting from the results or erosion and dilation correspondingly. F-opening and F-closing are formed as an algebraic combination of S-opening and S-closing and usual morphological opening and closing. It is proved that SM filters have the most mathematical properties of MM filters. The additional property of S-operators to preserve the connectivity and shape (edges) of restored image areas is provided. Some examples of S-morphological object extraction and F-morphological feature extraction are outlined. The significant improvement of extraction quality is demonstrated with comparison to usual MM operators. The example of special SM based on contour filtering is described.
