Shape Recognition with Spectral Distances
IEEE Transactions on Pattern Analysis and Machine Intelligence, 2011Recent works have shown the use of diffusion geometry for various pattern recognition applications, including nonrigid shape analysis. In this paper, we introduce spectral shape distance as a general framework for distribution-based shape similarity and show that two recent methods for shape similarity due to Rustamov and Mahmoudi and Sapiro are ...

Shape recognition in amblyopia
Vision Research, 1987The results of recent investigations of supra-threshold spatial vision in amblyopia have indicated that the amblyopic eye may be more disadvantaged than acuity or contrast detection measurements have suggested. We report here on the sensitivity of the amblyopic eye when performing tasks requiring the recognition of small spatial differences in thin ...

Attractor Networks for Shape Recognition
Neural Computation, 2001We describe a system of thousands of binary perceptrons with coarse-oriented edges as input that is able to recognize shapes, even in a context with hundreds of classes. The perceptrons have randomized feed-forward connections from the input layer and form a recurrent network among themselves.

IEEE Transactions on Image Processing, 2006
The problem of person recognition and verification based on their hand images has been addressed. The system is based on the images of the right hands of the subjects, captured by a flatbed scanner in an unconstrained pose at 45 dpi. In a pre-processing stage of the algorithm, the silhouettes of hand images are registered to a fixed pose, which ...

Viewer Independent Shape Recognition
IEEE Transactions on Pattern Analysis and Machine Intelligence, 1983An important problem in vision is to detect the presence of a known rigid 3-D object. The general 3-D object recognition task can be thought of as building a description of the object that must have at least two parts: 1) the internal description of the object itself (with respect to an object-centered frame); and 2) the transformation of the object ...

Recognition of Agricultural Objects by Shape
IEEE Transactions on Pattern Analysis and Machine Intelligence, 1983It is desired to enhance the outline of agricultural contraband in X-ray images of passenger luggage. Agricultural contraband consists of fruit, meats, animals, and plants. We suggest most contraband can be distinguished from other material by an elliptic, rather than rectangular, cross section.
