A Novel Approach to Shape Decomposition and Representation using Soft Morphological Filters

Shape decomposition and reconstruction are vital factors in image processing and analysis applications. A generalized skeleton transform allows a shape to be represented as a collection of modestly overlapped octagonal shape parts. One of the main problems with the existing algorithms is that they generate noise after decomposition. For ordinary images the rate of noise may not be effective but...

Shape Representation: Comparison between the Morphological Skeleton and Morphological Shape Decomposition

The morphological skeleton and morphological shape decomposition (MSD) are the two popular approaches for morphological shape representation. Each method represents an object as the union of a number of components, where each component is given by a locus of points dilated by a speciied structuring element homothetic. Anecdotal evidence suggests that for many objects, an MSD-based representatio...

Error Free Iterative Morphological Decomposition Algorithm for Shape Representation

Problem statement: A generalized skeleton transform allows a shape to be represented as a collection of modestly overlapped octagonal shape parts. One problem with several generalized Morphological skeleton transforms is that they generate noise after decomposition. The noise rate may not be effective for ordinary images; however this effect will be more when applied on printed or handwritten c...

Realisation of Soft Morphological Filters

A new technique for the realisation of soft morphological filters based on the majority gate algorithm is presented in this paper. A pipelined systolic array architecture suitable to perform soft morphological filtering is also presented. The processing times of the proposed hardware structure do not depend on the data window size and the required silicon area is linearly related to the number ...
