This paper describes the first results of a test implementation of the new multivariate B-splines as recently developed for quadratics and cubics. The surface scheme is based on blending functions and control points and allows us to model Ck-1-continuous piecewise polynomial surfaces of degree k over arbitrary triangulations of the parameter plane. The surface scheme exhibits both affine invariance and the convex hull property, and the control points can be used to manipulate the shape of the surface locally. Additional degrees of freedom in the underlying knot net allow for the modeling of discontinuities. Explicit formulas are given for the representation of polynomials and piecewise polynomials as linear combinations of B-splines.

The polyphase decomposition of a sequence is a useful tool in multirate signal processing such as in the design of computationally efficient decimators and interpolators, the design of analysis/synthesis filter banks, and the development of fast discrete transform algorithms. This paper reviews a recently introduced generalization of the polyphase decomposition concept and outlines some of its applications in the simplification of digital filtering algorithms such as the design and implementation of finite-impulse-response (FIR) digital filters, the design of decimators and interpolators, and discrete Fourier transform computations.

Traditional techniques for computing offsets are local in nature and lack good criteria for eliminating possible self-intersections of the offset. Methods based on integrating differential equations and image processing do not lack such criteria but seem to require constructing the solution in the ambient space, i.e., in one dimension larger than the offset. We investigate such methods.

This paper presents an image interpolation algorithm using the recently developed local cardinal interpolatory spline (LCIS). The procedures for constructing the LCIS basis are described for both univariate and bivariate cases. This new LCIS algorithm is very efficient and can be implemented easily. Without the need of a mapping procedure, this method is faster than any other polynomial interpolation approach. The C2 property of the LCIS also allows the gradient operator to be constructed for edge detection. Both image interpolation and edge detection algorithms are compared with existing methods in two different examples.

Detection of corners in an image is very useful in computer vision and pattern recognition. The existing algorithms for corner detection seem to be insufficient in many situations. The corner detection algorithm proposed in this paper is based on spline-wavelet decompositions. Corner and edge detectors are constructed from the 2-D wavelet transform coefficients. A somewhat sophisticated thresholding technique is applied to remove noise and minor irregularities in the images. Noise can be further reduced if additional processing is applied to the component images at all resolutions. Information on the edges and corners is contained in the component images in all the octaves to facilitate precise localization. A real-time wavelet decomposition algorithm is developed for the corner and edge detectors. It is very efficient and requires very little memory, since most of the computations involve only simple moving average operations and sub-sampling.

We present two algorithms to construct C1-smooth models of skeletal structures from CT/NMR voxel data. The boundary of the reconstructed models consists of a C1- continuous mesh of triangular algebraic surface patches. One algorithm first constructs C1-continuous piecewise conic contours on each of the CT/NMR data slices and then uses piecewise triangular algebraic surface patches to C1 interpolate the contours on adjacent slices. The other algorithm works directly in voxel space and replaces an initial C0 triangular facet approximation of the model with a highly compressed C1- continuous mesh of triangular algebraic surface patches. Both schemes are adaptive, yielding a higher density of patches in regions of higher curvature.

The principal orthogonal factor analysis or Karhunen-Loeve algorithm may be sped up by a low-complexity preprocessing step. A fast transform is selected from a large library of wavelet-like orthonormal bases, so as to maximize transform coding gain for an ensemble of vectors. Only the top few coefficients in the new basis, in order of variance across the ensemble, are then decorrelated by diagonalizing the autocovariance matrix. The method has computational complexity O(d2 log d + d'3) and O(d log d + d'2) respectively for training and classifying a d-dimensional system, where d' << d. One application is described, the reduction of an ensemble of 16,384 pixel face images to a 10 parameter space using a desktop computer, retaining 90% of the variance of the ensemble.

Earlier studies of the human vision system suggest that a complex object may be recognized from the qualitative features associated with its boundary. Since the human vision system uses qualitative features for object recognition, it is extremely robust to deformation caused by noise, obstruction, scale change, or optical distortion. We considered various qualitative descriptors for digital images. The descriptors developed in this research are based on the estimated curvature function from digital boundaries and can discriminate features such as straightness of a contour segment, perpendicularity of two contour segments, parallelness of two straight contour segments, parallelness of two curved contour segments in a global sense, and the direction of convergence if two straight contour segments are not parallel. We demonstrated that the qualitative descriptors developed in this paper can be applied for identification of elementary shapes, such as cylinders, bricks, cones, etc. We also discussed the recognition of more complex shapes after decomposing them into simpler components.

A classical approach formulates surface reconstruction in terms of a variational problem by using two-dimensional surfaces defined by generalized spline functions. We present such an approach in the case of range image segmentation. The distinction of our approach lies in the way the discontinuities are detected. The spline is constrained to stay within a certain maximal distance to the discrete measured data, but is free as long as the maximum distance is not reached. Discontinuity emerges on points where the maximum distance constrains the spline. This method leads to a relaxation algorithm that solves the segmentation iteratively, by locally applying a relation that is close to the diffusion equation in the case of the membrane spline. Being iterative and local, the algorithm is suited for parallelism. We applied the method to range data from laser scanners using two different surface models: the membrane spline (more adequate for polyhedric objects), and the thin plate spline (more adequate for curved objects). The results illustrate the practical performance of this method which is simple, parallel, and controlled by few parameters.

PERFORMANCE IN NOISE OF A DIFFUSION-BASED SHAPE DESCRIPTOR 2

PERFORMANCE IN NOISE OF A DIFFUSION-BASED SHAPE DESCRIPTOR

CONF ON curves AND surfaces IN computer vision AND graphics 2

A diffusion-like process, analogous to the thermodynamic diffusion of heat or of gas molecules, is used to describe the shape of two- or three-dimensional objects. It is effective at identifying extrema of curvature as would be used to segment the boundary, and also at characterizing the types of line segments that lie between the extrema. Both of those operations are essential for qualitative descriptions of images, as would be required by an approach based on geometrical icons (geons). The region need not be convex. The descriptor is invariant to several common transformations, including rotation. It can be implemented easily on parallel machines, does not pose problems with the definition of slope, and appears to be capable of dealing with the matching of partially occluded objects. The descriptor's performance is essentially independent of user-supplied parameters. It is shown that noise does not affect the accuracy of identification of the extrema -- a simple stopping rule for the process ensures that the structural parts of the boundary are preserved while the noise is suppressed. The procedure is compared and contrasted to scale-based boundary-description methods.
