Shape-based Invariant Texture Indexing
This paper introduces a new texture analysis scheme, which is invariant to local geometric and radiometric changes. The proposed methodology relies on the topographic map of images...

Grain Filters
Motivated by operators simplifying the topographic map of a function, we study the theoretical properties of two kinds of "grain" filters. The first category, discovered ...

Spontaneous symmetry breaking in self-organizing neural fields
Weextendthetheoryofself-organizingneuralfields in order to analyze the joint emergence of topography and feature selectivity in primary visual cortex through spontaneous symmetry b...

Gradients for Retinotectal Mapping
The initial activity-independent formation of a topographic map in the retinotectal system has long been thought to rely on the matching of molecular cues expressed in gradients i...

Locally invariant texture analysis from the topographic map
In this paper, we present a set of texture features that are locally invariant to similarity or affinity. The proposed indexing scheme relies on the topographic map, a shape-based...

Perceptible Level Lines and Isoperimetric Ratio
This paper introduces a simple criterion to select the most important level lines from the numerous set obtained with a topographic map. A topographic map gives a morphological an...
