5D.Clean

PURPOSE
Removes small features (typically around the size of a pixel) from an image. Can be useful for reducing (even eliminating, on a good day) certain kinds of noise. Also known as median filtering.

Before and after cleaning.

INPUT CLIP
Clip to clean.

X, Y Radius (Min: 1.0 Max: 120.0 Default: 1.0)
Sets the box dimension within which filtering is done. This 'box' is centred on every pixel of the image and its contents are used to find the corresponding output pixel.

PRINCIPLE OF OPERATION
The speed of operation is very dependent on the box size. With large box sizes, the output image will have the same median value over many adjacent pixels (typically) and will take on a scalloped appearance (not usually desirable). So, boxes that are just big enough to remove the unwanted noise are the best case.

Super cleaned!
