removes noise from image by applying a range-r Wiener filter.

assumes an additive noise power value ns.

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 rrow in height, and rcol in width.
  • In 3D, WienerFilter[image,{rslice,rrow,rcol}] uses range rslice in height, rrow in depth, and rcol in width.
  • WienerFilter takes a Padding option. The default setting is Padding->"Fixed".
