Parameter to tune the approximate size of the superpixel used for oversegmentation.

See also
  cv::ximgproc::createSuperpixelSLICK is a number of nearest-neighbor matches considered, when fitting a locally affine model. Usually it should be around 128. However, lower values would make the interpolation noticeably faster.

## ◆ setLambda()

Python:
| None | = | cv.ximgproc_EdgeAwareInterpolator.setSigma( | _sigma | )

Sigma is a parameter defining how fast the weights decrease in the locally-weighted affine fitting. Higher values can help preserve fine details, lower values can help to get rid of noise in the output flow.
