Detailed Description

LanczosPixelInterpolation uses the Lanczos interpolation algorithm (LanczosInterpolation) to interpolate pixel values from the nearest 2*n^2 neighbor pixels, where n is the filter order.

◆ LanczosPixelInterpolation() [1/2]

pcl::LanczosPixelInterpolation::LanczosPixelInterpolation	(	int	n = `3`,
		float	clamp = `0.3`
	)

inline

Constructs a LanczosPixelInterpolation object.

Parameters

n	Filter order (n >= 1). The Lanczos filter interpolates from the nearest (2*n)^2 mapped source pixels for each interpolation point. The default filter order is 3, which means that the interpolation uses a neighborhood of 36 source pixels.
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.
