# MinFilter

 MinFilterfilters image by replacing every value by the minimum in its range r neighborhood. MinFilterapplies min filtering to an array of data.
• 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.
