TYPE: COP
TITLE: Median COP

This operation applies a 3x3 or 5x5 median filter to the input image.  This
is used to remove "features" represented by individual pixels, such as "shot"
noise or pixel dropout.

Parameters:
    Filter Size       - Increases the size of the area over which it computes
                        the median (in pixels).

Local Variables:
    L   - Sequence length
    S   - Start of sequence
    E   - End of sequence
    IL  - Input sequence length
    SR  - Sequence frame rate
    NP  - Number of planes in sequence
    W,H - Width and height of image
    I   - Image index (0 at start frame)
    IT  - Image time (0 at start frame)
    AI  - Current plane array index
    PI  - Current plane index
    PC  - Num of channels in current plane
