Detailed Description

Filters off small noise blobs (speckles) in the disparity map.

Parameters

img	The input 16-bit signed disparity image
newVal	The disparity value used to paint-off the speckles
maxSpeckleSize	The maximum speckle size to consider it a speckle. Larger blobs are not affected by the algorithm
maxDiff	Maximum difference between neighbor disparity pixels to put them into the same blob. Note that since StereoBM, StereoSGBM and may be other algorithms return a fixed-point disparity map, where disparity values are multiplied by 16, this scale factor should be taken into account when specifying this parameter value.
buf	The optional temporary buffer to avoid memory allocation within the function.The base class for stereo correspondence algorithms.

Member Function Documentation

virtual void cv::stereo::StereoMatcher::compute	(	InputArray	left,
		InputArray	right,
		OutputArray	disparity
	)

pure virtual

Computes disparity map for the specified stereo pair.

Parameters

left	Left 8-bit single-channel image.
right	Right image of the same size and the same type as the left one.
disparity	Output disparity map. It has the same size as the input images. Some algorithms, like StereoBM or StereoSGBM compute 16-bit fixed-point disparity map (where each disparity value has 4 fractional bits), whereas other algorithms output 32-bit floating-point disparity map.
