Jitter

The call for this function is:-

vcm.Jitter(clip[ , int type = 1][,int jmax = frame width / 16][, data dense = "med"][, int wl = frame height / 8][, int stat = 0][, data speed = "med"] )

clip: Constant format RGB or YUV or Grey input with no subsampling.
type: 1 for random and 2 for sinusoidal Jitter
jmax: max amplitude of Jitter
dense: how frequent (number of rows) Jitter is present. "low", "med", "high"
wl: in type 2 wave length of sinusoid
stat: 1 for Jitter will be constant and 0 for move from frame to frame.
speed: if stat is set 0 then speed at which moves. "low', "med" and "high"
This function was developed on request from academia and is useful for testing deJitter function.
