[−][src]Function opencv::cudaarithm::subtract

pub fn subtract(
    src1: &dyn ToInputArray, 
    src2: &dyn ToInputArray, 
    dst: &mut dyn ToOutputArray, 
    mask: &dyn ToInputArray, 
    dtype: i32, 
    stream: &mut Stream
) -> Result<()>

Computes a matrix-matrix or matrix-scalar difference.

Parameters

  • src1: First source matrix or scalar.
  • src2: Second source matrix or scalar. Matrix should have the same size and type as src1 .
  • dst: Destination matrix that has the same size and number of channels as the input array(s). The depth is defined by dtype or src1 depth.
  • mask: Optional operation mask, 8-bit single channel array, that specifies elements of the destination array to be changed. The mask can be used only with single channel images.
  • dtype: Optional depth of the output array.
  • stream: Stream for the asynchronous version.
