Two- and three-dimensional patterns of the face by Peter W Hallinan( Book )

2 editions published in 1999 in English and held by 3 WorldCat member libraries worldwide

The human face is perhaps the most familiar and easily recognized object in the world, yet both its three-dimensional shape and its two-dimensional images are complex and hard to characterize. This book ties together applied mathematics, applied statistics, and engineering by applying general theories and concepts to the specific and familiar example of the human face. The authors include fully worked out examples of two approaches to face recognition, demonstrating the power of pattern theory and suggesting interesting new mathematics in the two-and three-dimensional aspects of the face
Fingerprints theorems for zero-crossings by A. L Yuille( Book )

2 editions published in 1983 in English and held by 2 WorldCat member libraries worldwide

It is proven that the scale map of the zero-crossings of almost all signals filtered by the second derivative of a gaussian of variable size determines the signal uniquely, up to a constant scaling and a harmonic function. The authors' proof provides a method for reconstructing almost all signals from knowledge of how the zero-crossing contours of the signal, filtered by a gaussian filter, change with the size of the filter. The proof assumes that the filtered signal can be represented as a polynomial of finite, albeit possibly very high, order. An argument suggests that this restriction is not essential. Stability of the reconstruction scheme is briefly discussed. The result applies to zero- and level-crossings of linear differential operators of gaussian filters. The theorem is extended to two dimensions, that is to images. These results are reminiscent of Logan's theorem. These imply that extreme of derivatives at different scales are a complete representation of a signal. (Author)
Shape from Shading, Occlusion and Texture by A. L Yuille( Book )

2 editions published in 1987 in English and held by 2 WorldCat member libraries worldwide

Shape from Shading, Occlusion and Texture are three important sources of depth information. We review and summarize work done on these modules

Massively parallel implementations of theories for apparent motion by Massachusetts Institute of Technology( Book )

1 edition published in 1987 in English and held by 1 WorldCat member library worldwide

We investigate two ways of solving the correspondence problem for motion using the assumptions of minimal mapping and rigidity. Massively parallel analog networks are designed to implement these theories. Their effectiveness is demonstrated with mathematical proofs and computer simulations. We discuss relevant psychophysical experiments. (Author)
A method for computing spectral reflectance by Massachusetts Institute of Technology( Book )

1 edition published in 1984 in English and held by 1 WorldCat member library worldwide

Psychophysical experiments show that the perceived colour of an object is relatively independent of the spectrum of the incident illumination and depends only on the surface reflectance. We demonstrate a possible solution to this underdetermined problem by expanding the illumination and surface reflection in terms of a finite number of basis functions. This yields a number of nonlinear equations for each colour patch. We show that given a sufficient number of surface patches with the same illumination it is possible to solve these equations up to an overall scaling factor. Generalizations to the spatial dependent situation are discussed. We define a method for detecting material changes and illustrate a way of detecting the colour of a material at its boundaries and propagating it inwards. Keywords include: color; material edges; basis functions; mondrians
Zero-crossings on lines of curvature by Massachusetts Institute of Technology( Book )

1 edition published in 1984 in English and held by 1 WorldCat member library worldwide

We investigate the relations between the structure of the image and events in the geometry of the underlying surface. We introduce some elementary differential geometry and use it to define a coordinate system on the object based on the lines of curvature. Using this coordinate system we can prove results connecting the extrema, ridges and zero-crossings in the image to geometrical features of the object. We show that extrema of the image typically correspond to points on the surface with zero Gaussian curvature and that parabolic lines often give rise to ridges, or valleys, in the image intensity. We show that directional zero-crossings of the image along the lines of curvature generally correspond to extrema of curvature along such lines. Keywords include: Photometric invariants; Zero crossings; Lines of curvature; and Parabolic lines
