DisparityWLSFilterImpl ignores minimal disparity #3995
Description
The current implementation of DisparityWLSFilterImpl seems to ignore the minimal disparity value. This is a snippet from the current code:
void DisparityWLSFilterImpl::init(double _lambda, double _sigma_color, bool _use_confidence, int l_offs, int r_offs, int t_offs, int b_offs, int _min_disp) { left_offset = l_offs; right_offset = r_offs; top_offset = t_offs; bottom_offset = b_offs; min_disp = _min_disp; valid_disp_ROI = Rect(); right_view_valid_disp_ROI = Rect(); min_disp=0; min_disp is first set correctly, but then it is overwritten.
The change is 10 years old, but maybe @sbokov is still around to comment on this.
