The purpose of this application is to apply Gaussian filters to an input image. The filters can compute the equivalent of a convolution between the input image and a gaussian Kernel. The filters in this application perform this process by a method far more efficient than kernel convolution. It is based on the use of a Recursive filter (IIR) that approximates very well the effect of convolving with a Gaussian kernel. A detailed description of the signal processing theory behind this filter can be found on the Report-1893 by R. Deriche at the INRIA web site. Postscript and PDF versions of the report are available.

Заранее спасибо.
