Remarks

  • Each pixel in the image is blurred based on neighborhood pixels. The radius value determines the size of the neighborhood to consider when blurring a pixel. The result is a blurred version of the original image.
  • The amount of blur is controlled by specifying the size of the neighborhood used for blurring or smoothing. The value of the Radius property determines the size and values of the mask.
  • This command supports 12 and 16-bit grayscale and 48 and 64-bit color images. Support for 12 and 16-bit grayscale and 48 and 64-bit color images is available only in the Document/Medical toolkits.
  • This command does not support 32-bit grayscale images.
