Detailed Description

Lanczos3LUTPixelInterpolation uses a Lanczos 3rd-order LUT-based interpolation algorithm (Lanczos3LUTInterpolation) to interpolate pixel values from the nearest 36 neighbor pixels. LUT-based interpolations are about three times faster than interpolations using function evaluations.

Constructor & Destructor Documentation

◆ Lanczos3LUTPixelInterpolation() [1/2]

pcl::Lanczos3LUTPixelInterpolation::Lanczos3LUTPixelInterpolation ( float clamp = 0.3F )

inline

Constructs a Lanczos3LUTPixelInterpolation object.

Parameters

clamp Clamping threshold. Clamping is applied to fix undershoot (aka ringing) artifacts. A value of this parameter within the [0,1] range enables clamping: The lower the clamping threshold, the more aggresive deringing effect is achieved. A negative threshold value disables the interpolation clamping feature. The default value is 0.3.
