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.

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.- Returns:
- automatically generated
-
setLambda
public void setLambda(double _lambda)
SEE: getLambda- Parameters:
_lambda
- automatically generated
-
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.- Returns:
- automatically generated
-
setSigmaColor
public void setSigmaColor(double _sigma_color)
SEE: getSigmaColor- Parameters:
_sigma_color
- automatically generated
-
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.- Returns:
- automatically generated
-
setLRCthresh
public void setLRCthresh(int _LRC_thresh)
SEE: getLRCthresh- Parameters:
_LRC_thresh
- automatically generated
-
getDepthDiscontinuityRadius
public int getDepthDiscontinuityRadius()
DepthDiscontinuityRadius is a parameter used in confidence computation. It defines the size of low-confidence regions around depth discontinuities.- Returns:
- automatically generated
-
setDepthDiscontinuityRadius
public void setDepthDiscontinuityRadius(int _disc_radius)
SEE: getDepthDiscontinuityRadius- Parameters:
_disc_radius
- automatically generated
-
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).- Returns:
- automatically generated
-
getROI
public Rect getROI()
Get the ROI used in the last filter call- Returns:
- automatically generated
