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

__fromPtr__

public static DisparityWLSFilter __fromPtr__(long addr)

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

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

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

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

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

setDepthDiscontinuityRadius

public void setDepthDiscontinuityRadius(int _disc_radius)

SEE: getDepthDiscontinuityRadius

Parameters:

_disc_radius - automatically generated

setLRCthresh

public void setLRCthresh(int _LRC_thresh)

SEE: getLRCthresh

Parameters:

_LRC_thresh - automatically generated

setLambda

public void setLambda(double _lambda)

SEE: getLambda

Parameters:

_lambda - automatically generated

setSigmaColor

public void setSigmaColor(double _sigma_color)

SEE: getSigmaColor

Parameters:

_sigma_color - automatically generated

finalize

protected void finalize()
                 throws java.lang.Throwable

Overrides:

finalize in class DisparityFilter

Throws:

java.lang.Throwable
