Detailed Description

Lanczos4LUTPixelInterpolation uses a Lanczos 4th-order LUT-based interpolation algorithm (Lanczos4LUTInterpolation) to interpolate pixel values from the nearest 64 neighbor pixels. LUT-based interpolations are about three times faster than interpolations using function evaluations.

Constructor & Destructor Documentation

◆ Lanczos4LUTPixelInterpolation() [1/2]

pcl::Lanczos4LUTPixelInterpolation::Lanczos4LUTPixelInterpolation ( float clamp = 0.3F )

inline

Constructs a Lanczos4LUTPixelInterpolation 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.
