Abstract
This contribution deals with the Heeger-Bergen pyramid-based texture
analysis/synthesis algorithm. It brings a detailed explanation of the
original algorithm tested on many characteristic examples. Our analysis
reproduces the original results, but also brings a minor improvement
concerning non-periodic textures. Inspired by visual perception
theories, Heeger and Bergen proposed to characterize a texture by its
first-order statistics of both its color and its responses to multiscale
and multi-orientation filters, namely the steerable pyramid. The
Heeger-Bergen algorithm consists in the following procedure: starting
from a white noise image, histogram matchings are performed to the noise
alternatively in both the image domain and steerable pyramid domain, so
that the corresponding histograms match the ones of the input texture.
