#include "stereo.hpp"
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. |

§ compute()
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. |
