Calculates weighted sum of input image and the accumulator acc so that acc becomes a running average of frame sequence: acc(x,y)=(1-alpha) * acc(x,y) + alpha * image(x,y) if mask(x,y)!=0 where alpha regulates update speed (how fast accumulator forgets about previous frames).

Parameters

image
Type: System..::..IntPtr
Input image, 1- or 3-channel, 8-bit or 32-bit floating point (each channel of multi-channel image is processed independently).
acc
Type: System..::..IntPtr
Accumulator of the same number of channels as input image, 32-bit or 64-bit floating-point.
alpha
Type: System..::..Double
Weight of input image
mask
Type: System..::..IntPtr
Optional operation mask
