Adds an image to the accumulator image

dst = cv.accumulate(src, dst)
dst = cv.accumulate(src, dst, 'OptionName',optionValue, ...)

Input

• src Input image of type uint8, uint16, single, or double, with any number of channels
• dst Input accumulator image with the same number of channels as input image, and a depth of single or double.

Output

• dst Output accumulator image.

Options

• mask Optional operation mask. Not set by default

The function adds src or some of its elements to dst:

dst(x,y) = dst(x,y) + src(x,y)  if mask(x,y)~=0

The function supports multi-channel images. Each channel is processed independently.

The function cv.accumulate can be used, for example, to collect statistics of a scene background viewed by a still camera and for the further foreground-background segmentation.
