Estimation of parameters in carbon sequestration models from net ecosystem exchange data
The use of net ecosystem exchange (NEE) data to estimate carbon transfer coefficients is investigated in the context of a deterministic compartmental carbon sequestration system. ...

Compressed Sensing and Redundant Dictionaries
This article extends the concept of compressed sensing to signals that are not sparse in an orthonormal basis but rather in a redundant dictionary. It is shown that a matrix, whic...

BRDC: binary representation of displacement code for line
: In raster graphics, a line is displayed as a sequence of connected pixels that best approximate the line with minimum deviation. The displacement code of a line is a sequence of ...

Gradient Convergence in Gradient methods with Errors
We consider the gradient method xt+1 = xt + t(st + wt), where st is a descent direction of a function f : n and wt is a deterministic or stochastic error. We assume that f is Lip...

A mean field annealing approach to robust corner detection
—This paper is an extension of our previous paper to improve the capability of detecting corners. We proposed a method of boundary smoothing for curvature estimation using a cons...
