This survey paper discusses the three-dimensional image processing challenges posed by
present and future immersive telecommunications, especially immersive video conferencing …

The paper addresses the problem of" class-based" image-based recognition and rendering
with varying illumination. The rendering problem is defined as follows: Given a single input …

We propose a classification method, called the nearest feature line (NFL), for face
recognition. Any two feature points of the same class (person) are generalized by the feature …

In this paper, we propose two novel methods for face recognition under arbitrary unknown
lighting by using spherical harmonics illumination representation, which require only one …

In the general case, a trilinear relationship between three perspective views is shown to
exist. The trilinearity result is shown to be of much practical use in visual recognition by …

The report addresses the problem of visual recognition under two sources of variability:
geometric and photometric. The geometric deals with the relation between 3D objects and …

How do observers recognize faces despite dramatic image variations that arise from
changes in illumination? This paper examines (1) whether face recognition is sensitive to …

We consider the problem of clustering data into k≥ 2 clusters given complex relations—
going beyond pairwise—between the data points. The complex n-wise relations are …

Image analysis and graphics synthesis can be achieved with learning techniques using
directly image examples without physically-based, 3D models. In our technique:--the …

A key problem in recognition is that the image of an object depends on the lighting
conditions. We investigated whether recognition is sensitive to illumination using 3-D objects …
