Calculates the weighted sum of two arrays

dst = cv.addWeighted(src1, alpha, src2, beta, gamma)
dst = cv.addWeighted(..., 'OptionName',optionValue, ...)

Input

• src1 first input array.
• alpha weight for the first array elements.
• src2 second input array of the same size and channel number as src1.
• beta weight for the second array elements.
• gamma scalar added to each sum.

Output

• dst output array that has the same size and number of channels as the input arrays.

Options

• DType optional depth of the output array: uint8, int16, double, etc. Must be specified if input arrays are of different types. When both input arrays have the same depth, DType can be set to -1, which will be equivalent to class(src1). default -1

The function cv.addWeighted calculates the weighted sum of two arrays as follows:

dst(I) = saturate(src1(I)*alpha + src2(I)*beta + gamma)

where I is a multi-dimensional index of array elements. In case of multi-channel arrays, each channel is processed independently.

Note: Saturation is not applied when the output array has the depth int32. You may even get result of an incorrect sign in the case of overflow.
