Detailed Description

template<template< class > class A>
struct Simd::Pyramid< A >

The Pyramid structure provides storage and manipulation of pyramid images.

The pyramid is a series of gray 8-bit images. Every image in the series is lesser in two times than previous. The structure is useful for image analysis.
