The use of visual representations in which pixel-size and local neighborhood topology are not constant is termed space-variant vision. This is the dominant visual architecture in all higher vertebrate visual systems, and is coming to play an important role in real-time active vision applications in the form of log-polar, foveating pyramid, and related approaches to machine vision. The breaking ...

In this paper, we propose a novel approach to generating topology preserving mapping of structural shapes using the self-organising maps (SOM). The structural information of the geometrical shapes is captured by the relational vectors. These relational attribute vectors are quantised using an SOM. Using this quatisation SOM, a histogram is generated for every shape. These histograms are treated...

In this paper, we propose a novel approach to generate the topology-preserving mapping of structural shapes using self-organizing maps (SOMs). The structural information of the geometrical shapes is captured by relational attribute vectors. These vectors are quantised using an SOM. Using this SOM, a histogram is generated for every shape. These histograms are treated as inputs to train another ...

The use of visual representations in which retinal neurons receptive elds are not constant over the visual eld is universal in the visual systems of higher vertebrates, and is coming to play an important role in active vision applications. The breaking of translation symmetry that is unavoidably associated with non-uniform sampling presents a major algorithmic complication for image processing....

In this work, we design a multi-category inverse neural network to map ordered periodic structures physical parameters. The model consists of two parts, classifier and Structure-Parameter-Mapping (SPM) subnets. is used identify structures, the SPM subnets are predict parameters for desired structures. We also present an extensible reciprocal-space data augmentation method guarantee rotation tra...

We determined the structural basis for the presence of electrophoretically-distinct, antigenically-related forms of invariant chains in Ia oligomers, and established the mechanisms by which they can be expressed from a single gene. S1 nuclease protection assays indicated that, in B cells, transcription of this gene initiates at a minimum of three sites. Thus, unlike previously thought, invarian...
