pub fn sqrt(src: &impl ToInputArray, dst: &mut impl ToOutputArray) -> Result<()>Expand description
Calculates a square root of array elements.
The function cv::sqrt calculates a square root of each input array element. In case of multi-channel arrays, each channel is processed independently. The accuracy is approximately the same as of the built-in std::sqrt .
Parameters
- src: input floating-point array.
- dst: output array of the same size and type as src.
