public class MPSImageGaussianPyramid
extends MPSImagePyramid

MPSImageGaussianPyramid

A Gaussian image pyramid is constructed as follows: The mipmap level zero is the source of the operation and is left untouched and the subsequent mipmap levels are constructed from it recursively: [@code] mip[ level = n + 1 ] = Downsample( filter( mip[ level = n ] ) ), where [@endcode] "filter()" applies a filter with the specified convolution kernel and "Downsample()" removes odd rows and columns from the input image. The default convolution filter kernel for this operation is [@code] k = w w^T, where w = [ 1/16, 1/4, 3/8, 1/4, 1/16 ]^T, [@endcode] but the user may also tweak this kernel with a @ref centerWeight parameter: 'a': [@code] k = w w^T, where w = [ (1/4 - a/2), 1/4, a, 1/4, (1/4 - a/2) ]^T [@endcode] or the user can provide a completely custom kernel.

This procedure is continued until every mipmap level present in the image texture are filled with the pyramid levels.

In case of the Gaussian pyramid the user must run the operation in-place using: [@ref] MPSUnaryImageKernel::encodeToCommandBuffer:inPlaceTexture:fallbackCopyAllocator:, where the fallback allocator is ignored.
