Factory method to create instance of DisparityWLSFilter

obj = cv.DisparityWLSFilter(matcher_left)
obj = cv.DisparityWLSFilter(use_confidence)

Input

• matcher_left stereo matcher instance that will be used with the filter. An object of one of the following classes:
  • cv.StereoBM stereo correspondence using the block matching algorithm.
  • cv.StereoSGBM stereo correspondence using the semi-global block matching algorithm.
• use_confidence Boolean. Filtering with confidence requires two disparity maps (for the left and right views) and is approximately two times slower. However, quality is typically significantly better.

The first variant is a convenience factory method that creates an instance of DisparityWLSFilter and sets up all the relevant filter parameters automatically based on the matcher instance. Currently supports only cv.StereoBM and cv.StereoSGBM.

The second variant is a more generic factory method, that create instance of DisparityWLSFilter and execute basic initialization routines. When using this method you will need to set-up the ROI, matchers and other parameters by yourself.
