Provided methods

fn calc(
    &mut self,
    i0: &dyn ToInputArray,
    i1: &dyn ToInputArray,
    flow: &mut dyn ToInputOutputArray
) -> Result<()>

Calculates an optical flow.

Parameters

  • I0: first 8-bit single-channel input image.
  • I1: second input image of the same size and the same type as prev.
  • flow: computed flow image that has the same size as prev and type CV_32FC2.

fn collect_garbage(&mut self) -> Result<()>

Releases all inner buffers.
