Fuzzy medial axis transformation ( FMAT ) : Image representation , skeleton extraction and uncertainty management in computer vision SANKAR
The problem of extraction of medial axis transformation of a gray image with reference to skeletonization, image representation and uncertainty management in a vision system has been addressed. The Fuzzy Medial Axis Transformation (FMAT) of a fuzzy set f is a set of fuzzy disks whose sup is f. Unfortunately, specifying the FMAT sometimes requires more storage space than specifying f itself. The...
متن کاملFuzzy Medial Axis Transformation (FMAT): Practical feasibility
Abslracl: The Fuzzy Medial Axis Transformation (FMAT) of a fuzzy set f is a set of fuzzy disks whose sup is f. Unforlunately, specifying the FMAT sometimes requires more storage space than specifying.f itself. The present paper describes some techniques Lo improve the compact representatiou of FMAT; thereby making it practically feasible and useful. The algorithms involve reduction of redundanc...
متن کاملA fuzzy medial axis transformation based on fuzzy disks
Pal, S.K. and A. Rosenfeld, A fuzzy medial axis transformation based on fuzzy disks, Pattern Recognition Letters 12 (1991) 585-590. A fuzzy disk with cenler P is a fuzzy set in which membership depends only on distance from P. For any fuzzy set 1. there is a maximal fuzzy disk g~ ~j centered al every point P, and j is the sup of the g~'s. (Moreover, if j is fuzzy convex, so is every g~, bUI nOl...
متن کاملComparative study on morphological skeletonization and fuzzy medial axis transformation
In this paper, we make a comparative study on morphological skeletonization (MSK) and fuzzy medial axis transformation (FMAT). Methods have been proposed to construct convex FMAT from the morphological skeleton points and to translate FMAT to MSK, respectively. For the case of translating MSK to convex FMAT, the experimental results reveal that the combination of the proposed method and the red...
متن کاملA Straight Skeleton Approximating the Medial Axis
We propose the linear axis, a new skeleton for polygonal shapes. It is related to the medial axis and the straight skeleton, being the result of a wavefront propagation process. The wavefront is linear and propagates by translating edges at constant speed. The initial wavefront is an altered version of the original polygon: zero-length edges are added at reflex vertices. The linear axis is a su...
