the proceedings contain 39 papers. the topics discussed include: quasi 4-8 subdivision surfaces;mesh collapse compression;an algorithm for two-dimensional mesh generation for arbitrary regions with cracks;interpolation of scattered data: investigating alternatives for the modified shepard method;visualizing the unseen body: architectural potentials of data modeling;interval methods for ray casting implicit surfaces with affine arithmetic;efficient visualization of graphical objects;multiple display viewing architecture for virtual environments over heterogeneous networks;fast digital perspective shell rendering;piecewise trilinear deformation of tomographic models;control point assessment for image registration;and a methodology for 3D registration of range images for object visualization.
this paper describes an approach to face detection, which is the first stage of any fully automated human face recognition system. We propose several enhancements to a feature-based approach described by K.C. Yow and ...

this paper presents a new image data fusion method that aims to combine images with different spatial and spectral resolutions. It is based on a projection onto the subspace of the set of solutions of an underdetermin...

Presents several extensions of the basic control point assessment (CPA) algorithm. First, we compare CPA to standard corner detection algorithms and then turn to the question of selecting control points with adequate ...

In automatic fractal image compression, most of the encoding time is spent on finding the best match between each range block and the domain blocks. We propose the use of the local complexity of the image domain block...
