[−][src]Function opencv::core::multiply

pub fn multiply(
    src1: &dyn ToInputArray, 
    src2: &dyn ToInputArray, 
    dst: &mut dyn ToOutputArray, 
    scale: f64, 
    dtype: i32
) -> Result<()>

Calculates the per-element scaled product of two arrays.

The function multiply calculates the per-element product of two arrays:

block formula

There is also a @ref MatrixExpressions -friendly variant of the first function. See Mat::mul .

For a not-per-element matrix product, see gemm .

Note: Saturation is not applied when the output array has the depth CV_32S. You may even get result of an incorrect sign in the case of overflow.

Parameters

  • src1: first input array.
  • src2: second input array of the same size and the same type as src1.
  • dst: output array of the same size and type as src1.
  • scale: optional scale factor.
  • dtype: optional depth of the output array
