CvInvokeAccumulateWeighted Method |
Calculates weighted sum of input src 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
- src
- Type: Emgu.CVIInputArray
Input image, 1- or 3-channel, 8-bit or 32-bit floating point (each channel of multi-channel image is processed independently). - dst
- Type: Emgu.CVIInputOutputArray
Accumulator of the same number of channels as input image, 32-bit or 64-bit floating-point. - alpha
- Type: SystemDouble
Weight of input image - mask (Optional)
- Type: Emgu.CVIInputArray
Optional operation mask
