[−][src]Function opencv::imgproc::accumulate_weighted

pub fn accumulate_weighted(
    src: &dyn ToInputArray, 
    dst: &mut dyn ToInputOutputArray, 
    alpha: f64, 
    mask: &dyn ToInputArray
) -> Result<()>

Updates a running average.

The function calculates the weighted sum of the input image src and the accumulator dst so that dst becomes a running average of a frame sequence:

block formula

That is, alpha regulates the update speed (how fast the accumulator "forgets" about earlier images). The function supports multi-channel images. Each channel is processed independently.

Parameters

  • src: Input image as 1- or 3-channel, 8-bit or 32-bit floating point.
  • dst: %Accumulator image with the same number of channels as input image, 32-bit or 64-bit floating-point.
  • alpha: Weight of the input image.
  • mask: Optional operation mask.
