Detailed Description
The Volterra / Unsharp filter process uses a quadratic Volterra filter to enhance edges.
The output of the Volterra filter is approximately equivalent to the product of the local mean and a high-pass filter. The result is then scaled and added to the original input image value to produce the final output.
