Median

Weighted Median Filter:It is same as median filter, only difference is the mask is not empty. It will having some weight (or values) and averaged.The steps to perform weighted median filtering are as follows:1) Assume a 3x3 weighted mask.2) Place the mask at the left hand corner.3) After...

Some curve fitting or smoothing tools can benefit from knowledge of the noise variance to expect on your data. Kalman filters use this information, also some spline fitting tools. So I wrote a function to extract the noise variance from a signal vector. It also works on any specified dimension of...
