Frame domain signal processing: Framework and applications
Besides basis expansions, frames representations play a key role in signal processing. We thus consider the problem of frame domain signal processing, which is more complex and ch...

Contour Tracking in Clutter: A Subset Approach
A new method for tracking contours of moving objects in clutter is presented. For a given object, a model of its contours is learned from training data in the form of a subset of c...

Single antenna power measurements based direction finding
Abstract--In this paper, the problem of estimating direction-ofarrival (DOA) of multiple uncorrelated sources from single antenna power measurements is addressed. Utilizing the fac...

The measurement of ranks and the laws of iterated contraction
: Ranking theory delivers an account of iterated contraction; each ranking function induces a specific iterated contraction behavior. The paper shows how to reconstruct a ranking f...

Decompositions of graphs of functions and fast iterations of lookup tables
We show that every function f implemented as a lookup table can be implemented such that the computational complexity of evaluating f m(x) is small, independently of m and x. The ...
