Finding the sparsest solution for an under-determined linear system of equations D = s is of interest in many applications. This problem is known to be NP-hard. Recent work studie...
We present an interior-point penalty method for nonlinear programming (NLP), where the merit function consists of a piecewise linear penalty function (PLPF) and an 2-penalty functi...
In order to properly calibrate an electronic camera for a variety of illuminantsit is necessary to estimate the spectral sensitivity of the camera. This spectral characterisation ...
