Class DisparityWLSFilter

  • public class DisparityWLSFilter
    extends DisparityFilter
    Disparity map filter based on Weighted Least Squares filter (in form of Fast Global Smoother that is a lot faster than traditional Weighted Least Squares filter implementations) and optional use of left-right-consistency-based confidence to refine the results in half-occlusions and uniform areas.

    • Method Detail

      • getLambda

        public double getLambda()
        Lambda is a parameter defining the amount of regularization during filtering. Larger values force filtered disparity map edges to adhere more to source image edges. Typical value is 8000.

        public void setLambda​(double _lambda)

      • getSigmaColor

        public double getSigmaColor()
        SigmaColor is a parameter defining how sensitive the filtering process is to source image edges. Large values can lead to disparity leakage through low-contrast edges. Small values can make the filter too sensitive to noise and textures in the source image. Typical values range from 0.8 to 2.0.

        public void setSigmaColor​(double _sigma_color)

      • getLRCthresh

        public int getLRCthresh()
        LRCthresh is a threshold of disparity difference used in left-right-consistency check during confidence map computation. The default value of 24 (1.5 pixels) is virtually always good enough.

      • getDepthDiscontinuityRadius

        public int getDepthDiscontinuityRadius()
        DepthDiscontinuityRadius is a parameter used in confidence computation. It defines the size of low-confidence regions around depth discontinuities.

      • getConfidenceMap

        public Mat getConfidenceMap()
        Get the confidence map that was used in the last filter call. It is a CV_32F one-channel image with values ranging from 0.0 (totally untrusted regions of the raw disparity map) to 255.0 (regions containing correct disparity values with a high degree of confidence).

        Get the ROI used in the last filter call
