WienerFilter

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 OptionsDetails 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".
