A method for filtering video noise is adapted to filter noise of a plurality of images of a video stream. The base permits the appliance to be ready for mounting and includes a cured layer of polymer resin mounted on the appliance and an uncured layer of substantially the same polymer resin over the cured layer which when cured becomes integral with the cured layer in attaching the appliance to a bony part of the body. The input values are gated with the coefficients to form output values.
