FilterUnsharpBorder(NPPImage_16sC1, Single, Single, Single, Single, NppiBorderType, CudaDeviceVariable<Byte>)

Filters the image using a unsharp-mask sharpening filter kernel with border control.

Smooth the original image with a Gaussian filter, with the width controlled by the nRadius.

Apply any clipping needed on the high-pass image, as controlled by the nThreshold.

Add a certain percentage of the high-pass filtered image to the original image, with the percentage controlled by the nWeight. In pseudocode this algorithm can be written as:

HighPass = Image - Gaussian(Image)

Result = Image + nWeight * HighPass * ( |HighPass| >= nThreshold )
