public class MPSImageLaplacianPyramidAdd
extends MPSImageLaplacianPyramid

MPSImageLaplacianPyramidAdd

The MPSImageLaplacianPyramidAdd class is responsible for reconstruction of Gaussian pyramid from the Laplacian pyramid supplied in the source texture. Mathematically it is the inverse of the process specified in the discussion section for MPSImageLaplacianPyramid.

It is an iterative process, starting from the top mip-level and on each iteration feeding off both the LaplacianMipLevel[l] data coming directly from the source and GaussianMipLevel[l + 1] just written to the destination on the previous iteration :

GaussianMipLevel[l] := LaplacianRangeScale^-1(LaplacianMipLevelStored[l], laplacianBias, laplacianScale) + Interpolate(GaussianMipLevel[l + 1])

As initial state for the first iteration only, the data for GaussianMipLevel[l + 1] in the formula above is provided in the LaplacianMipLevel[#top] level. This corresponds to the special handling of the top mip-level of Gaussian pyramid discussed for MPSImageLaplacianPyramidSubtract. Just like for MPSImageLaplacianPyramidSubtract, if the destination texture needs to contain all mip-level of the Gaussian pyramid including the top level, it can be just from the source texture.
