Adds the per-element product of two input images to the accumulator

dst = cv.accumulateProduct(src1, src2, dst)
dst = cv.accumulateProduct(src1, src2, dst, 'OptionName',optionValue, ...)

Input

• src1 First input image, 1- or 3-channel, 8-bit or 32-bit floating point.
• src2 Second input image of the same type and the same size as src1.
• dst Input accumulator with the same number of channels as input images, 32-bit or 64-bit floating-point.

Output

• dst Output accumulator image.

Options

• mask Optional operation mask. Not set by default

The function adds the product of two images or their selected regions to the accumulator dst:

dst(x,y) = dst(x,y) + src1(x,y)*src2(x,y)  if mask(x,y)~=0

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