Mutable methods for crate::cudaoptflow::CUDA_NvidiaOpticalFlow_1_0

Required Methods§

source

fn as_raw_mut_CUDA_NvidiaOpticalFlow_1_0(&mut self) -> *mut c_void

Provided Methods§

source

fn up_sampler( &mut self, flow: &impl ToInputArray, image_size: Size, grid_size: i32, upsampled_flow: &mut impl ToInputOutputArray ) -> Result<()>

The NVIDIA optical flow hardware generates flow vectors at granularity gridSize, which can be queried via function getGridSize(). Upsampler() helper function converts the hardware-generated flow vectors to dense representation (1 flow vector for each pixel) using nearest neighbour upsampling method.

Parameters
  • flow: Buffer of type CV_16FC2 containing flow vectors generated by calc().
  • imageSize: Size of the input image in pixels for which these flow vectors were generated.
  • gridSize: Granularity of the optical flow vectors returned by calc() function. Can be queried using getGridSize().
  • upsampledFlow: Buffer of type CV_32FC2, containing upsampled flow vectors, each flow vector for 1 pixel, in the pitch-linear layout.
