FUNCTIONaccumulateProduct

RETURN TYPEvoid

Call structure. A void return can still write to destination arguments. The parameter descriptions define inputs, outputs and ownership.

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

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

\texttt{dst} (x,y)  \leftarrow \texttt{dst} (x,y) +  \texttt{src1} (x,y)  \cdot \texttt{src2} (x,y)  \quad \text{if} \quad \texttt{mask} (x,y)  \ne 0

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

accumulateProduct(src1: Mat, src2: Mat, dst: Mat, mask: Mat): void;

2 available overloads

accumulateProduct(src1: Mat, src2: Mat, dst: Mat): void;

accumulateProduct(src1: Mat, src2: Mat, dst: Mat, mask: Mat): void;

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/output value, modified by the native operation. %Accumulator image with the same number of channels as input images, 32-bit or 64-bit floating-point.
mask: Optional operation mask.
