BUILT-IN MATHEMATICA SYMBOL
WienerFilter[image, r]
removes noise from image by applying a range-r Wiener filter.
WienerFilter[image, r, ns]
assumes an additive noise power value ns.
WienerFilter[data, ...]
applies Wiener filtering to an array of data.
Details and Options
- WienerFilter[image, r] applies a Wiener filter using a
×
convolution kernel. - WienerFilter works with arbitrary grayscale and multichannel images, operating separately on each channel.
- WienerFilter works with 3D as well as 2D images, and also with numerical data arrays of any rank.
- In 2D, WienerFilter[image, {rrow, rcol}] uses range
in height, and 
in width. - In 3D, WienerFilter[image, {rslice, rrow, rcol}] uses range
in height, 
in depth, and 
in width. - WienerFilter takes a Padding option. The default setting is Padding->"Fixed".
