Self-similar progressive image sampling schemes that have been recently proposed for holographic image representations are shown to generate two-dimensional low discrepancy sequen- ces. The discrepancy of a planar set of points is a measure of the un

Given A-spline curves and A-patch surfaces that are implicitly defined on triangles and tetrahedra, we determine their NURBS representations. We provide a trimmed NURBS form for A-spline curves and a parametric tensor-product NURBS form for A-patch s

We present an adaptive, hierarchical Hh-multiresolution reconstruction algorithm to model shell surface objects from a matched pair of triangulated surfaces. Shell surfaces are an interval of contours of trivariate functions with prismatic support. I

Curves that pass through specified locations with specified orientations and minimize an energy functional are called elastica. While physical splines readily assume minimal energy configurations, finding the numerical solutions of variational proble

Trilinear relationships among the image point coordinates obtained by perspective projection of several feature points over three views have been investigated, and it has been shown that seven point correspondences are sufficient to determine the coe

Lossy transform compression of images is successful and widespread. The JPEG standard uses the discrete cosine transform on blocks of the image and a bit allocation process that takes advantage of the uneven energy distribution in the transform domai

Several unconventional ideas for viewer/camera pose estimation are discussed. The methods proposed so far advocate the use of advanced image processing for identification and precise location of calibration objects in the images acquired, and base po

The image of an object and of the shadow it casts on a planar surface provides important cues for three-dimensional (3D) stance recovery. We assume that the position of the plane on which the shadow lies with respect to a pinhole camera is known and

We investigate how a given fixed number of points should be located in space so that the pose of a camera viewing them from unknown locations can be estimated with the greatest accuracy. We show that optimum solutions are obtained when the points for

A-splines are implicit real algebraic curves in Bernstein-Bezier (BB) form that are smooth. We develop A-spline curve models using various energy formulations, incorporating bending and stretching energy, based on the theory of elasticity. The attemp
