TLDR
This correspondence provides some theoretical aspects of the problem of picture segmentation that are practically unsolvable in its more general case formulation.Abstract:
The problem of picture segmentation is widely believed to be practically unsolvable in its more general case formulation. However, as far as the authors know no formal argumentation has yet been given to this belief related to the segmentation problem. This correspondence provides some theoretical aspects of this phenomenon.read more

Image segmentation based on oscillatory correlation
DeLiang Wang,David Terman +1 more
TL;DR: It is argued that LEGION provides a novel and effective framework for image segmentation and figure-ground segregation and exhibits a natural capacity in segmenting images.

Segmentation of textured images and Gestalt organization using spatial/spatial-frequency representations
T. R. Reed,Harry Wechsler +1 more
TL;DR: Experimental results in the area of texture segmentation and Gestalt grouping using the Wigner distribution are presented, proving the feasibility of using s/sf representations for low-level (early, preattentive) vision.

Face Authentication Using Recognition-by-Parts, Boosting, and Transduction
Harry Wechsler,Fayin Li +1 more
TL;DR: A robust recognition-by-parts authentication system for comparing and authenticating a test image with at least one training image is disclosed and applies the concepts of recognition- by-parts, boosting, and transduction.

Weight adaptation and oscillatory correlation for image segmentation
Ke Chen,DeLiang Wang,Xiuwen Liu +2 more
TL;DR: It is shown that weight adaptation plays the roles of noise removal and feature preservation and the scheme is insensitive to termination time and the resulting dynamic weights in a wide range of iterations lead to the same segmentation results.

The Consistent Labeling Problem: Part II
TL;DR: It is shown that Latin square puzzles, finding N-ary relations, graph or auto-mata homomorphisms, graph colorings, as well as determining satisfiability of propositional logic statements and solving scene and edge labeling problems, are all special cases of the general consistent labeling problem.
