Cv2FilterSpeckles Method

filters off speckles (small regions of incorrectly computed disparity)

Namespace:  OpenCvSharp
Assembly:  OpenCvSharp (in OpenCvSharp.dll) Version: 1.0.0
Syntax
public static void FilterSpeckles(
	InputOutputArray img,
	double newVal,
	int maxSpeckleSize,
	double maxDiff,
	InputOutputArray buf = null
)

Parameters

img
Type: OpenCvSharpInputOutputArray
The input 16-bit signed disparity image
newVal
Type: SystemDouble
The disparity value used to paint-off the speckles
maxSpeckleSize
Type: SystemInt32
The maximum speckle size to consider it a speckle. Larger blobs are not affected by the algorithm
maxDiff
Type: SystemDouble
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 (Optional)
Type: OpenCvSharpInputOutputArray
The optional temporary buffer to avoid memory allocation within the function.
