The paper addresses the problem of “class-based” imagebased recognition and rendering with varying illumination. The rendering problem is defined as follows: given a single input image of an object,… (More)

We discuss the problem of ranking instances with the use of a “large margin” principle. We introduce two main approaches: the first is the “fixed margin” policy in which the margin of the closest… (More)

| 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 alignment |… (More)

We consider the problem of learning with instances defined over a space of sets of vectors. We derive a new positive definite kernel f (A,B) defined over pairs of matrices A,B based on the concept of… (More)

We consider the problem of finding a matching between two sets of features, given complex relations among them, going beyond pairwise. Each feature set is modeled by a hypergraph where the complex… (More)

We describe the functional and architectural breakdown of a monocular pedestrian detection system. We describe in detail our approach for single-frame classification based on a novel scheme of… (More)

We derive algorithms for finding a non-negative n-dimensional tensor factorization (n-NTF) which includes the non-negative matrix factorization (NMF) as a particular case when n = 2. We motivate the… (More)

We present a new method for synthesizing novel views of a 3D scene from few model images in full correspondence. The core of this work is the derivation of a tensorial operator that describes the… (More)
