Provided methods

pub fn calc(
    &mut self,
    prev_img: &dyn ToInputArray,
    next_img: &dyn ToInputArray,
    prev_pts: &dyn ToInputArray,
    next_pts: &mut dyn ToInputOutputArray,
    status: &mut dyn ToOutputArray,
    err: &mut dyn ToOutputArray
) -> Result<()>[src]

Calculates a sparse optical flow.

Parameters

  • prevImg: First input image.
  • nextImg: Second input image of the same size and the same type as prevImg.
  • prevPts: Vector of 2D points for which the flow needs to be found.
  • nextPts: Output vector of 2D points containing the calculated new positions of input features in the second image.
  • status: Output status vector. Each element of the vector is set to 1 if the flow for the corresponding features has been found. Otherwise, it is set to 0.
  • err: Optional output vector that contains error response for each point (inverse confidence).

C++ default parameters

  • err: cv::noArray()
