Anti-aliasing with stratified B-spline filters of arbitrary degree [PDF]
, 2006 A simple and elegant method is presented to perform anti-aliasing in raytraced images. The method uses stratified sampling to reduce the occurrence of artefacts in an image and features a B-spline filter to compute the final luminous intensity at each ...

Filtered wavelet thresholding methods
Journal of Computational and Applied Mathematics, 2004 The quality of a denoised image depends on several factors, including especially the choice of the thresholding parameter \(\lambda\) and the use of a suitable filter function. In this paper the authors study a piecewise quadratic function of \(\lambda\) and an exponential function of \(\lambda\) that can be satisfyingly used as filters instead of the ...

Synthesis method for matching filters [PDF]
2017 IEEE MTT-S International Microwave Symposium (IMS), 2017 The aim of this paper is to develop an exact synthesis technique for matching filters in connexion with the use of single band antennas. A certified algorithm based on Youla's matching theory and convex optimization is presented. A practical example is considered with the synthesis of a matching filter in SIW technology used behind a microstrip patch ...
