说明： 这是自然图像统计这本书上的相关代码，相信对大家会很有用。
(This is a book on natural image statistics related to the code, I believe we will be very useful.)

This directory contains the Matlab(TM) code and natural image data to
reproduce most of the experiments on in chapters 1-11 and Section 13.1
of the book "Natural Image Statistics" by Hyvarinen, Hurri, and Hoyer,
published by Springer.
Code by Aapo Hyvarinen partly based on code by Patrik O. Hoyer
and rotavg.m code courtesy of Bruno Olshausen
This is version 1.0, 11 Dec 2008, run with Matlab 7.5.0
MAIN FILE: figures.m
Running this file will do all the main experiments
DATA DIRECTORY: data/
This directory contains the natural images used in the experiments
SAMPLING: sampleimages.m
Sample patches from images in directory "data"
PREPROCESSING: removeDC.m
Remove DC from image patches
Note: there is no single command for whitening the data, see figures.m
on how to use the results from pca.m to whiten your data
MAIN ALGORITHMS:
pca.m %principal component analysis
ica.m %FastICA for whitened data
isa_est.m %estimation of ISA model for whitened data
tica.m %estimation of topographic ICA for whitened data
overcomplete.m %estimation of energy-based overcomplete model for whitened data
OTHER FILES:
subroutines of the above, including plotting and terminal reporting commands.
