Mutable methods for crate::video::DenseOpticalFlow

Required Methods§

source

fn as_raw_mut_DenseOpticalFlow(&mut self) -> *mut c_void

Provided Methods§

source

fn calc( &mut self, i0: &impl ToInputArray, i1: &impl ToInputArray, flow: &mut impl 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.
source

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

Releases all inner buffers.
