Simple one-line Fast Bilateral Solver filter call. If you have multiple images to filter with the same guide then use FastBilateralSolverFilter interface to avoid extra computations.

Parameters

  • guide: image serving as guide for filtering. It should have 8-bit depth and either 1 or 3 channels.

  • src: source image for filtering with unsigned 8-bit or signed 16-bit or floating-point 32-bit depth and up to 4 channels.

  • confidence: confidence image with unsigned 8-bit or floating-point 32-bit confidence and 1 channel.

  • dst: destination image.

  • sigma_spatial: parameter, that is similar to spatial space sigma (bandwidth) in bilateralFilter.

  • sigma_luma: parameter, that is similar to luma space sigma (bandwidth) in bilateralFilter.

  • sigma_chroma: parameter, that is similar to chroma space sigma (bandwidth) in bilateralFilter.

  • lambda: smoothness strength parameter for solver.

  • num_iter: number of iterations used for solver, 25 is usually enough.

  • max_tol: convergence tolerance used for solver.

For more details about the Fast Bilateral Solver parameters, see the original paper BarronPoole2016.

Note: Confidence images with CV_8U depth are expected to in [0, 255] and CV_32F in [0, 1] range.
