MinFilter

MinFilter
filters image by replacing every value by the minimum in its range r neighborhood.
MinFilter
applies min filtering to an array of data.
MORE INFORMATION
  • MinFilter finds the minimum in × blocks centered on each pixel.
  • At the edges of an image, MinFilter uses smaller neighborhoods.
  • MinFilter uses neighborhoods with vertical range and horizontal range .
  • For multichannel images, MinFilter replaces each pixel by a pixel in its neighborhood that has the minimum total intensity, averaged over all channels.
  • In MinFilter, data can be an array of any rank.
