## Readme

- This simulation evaluate four patterns: Circular pattern, [Levin 2007], [Veeraraghavan 2008], [Zhou 2009]

- This is also a demo code of Weiner Deconvolution Algorithm using 1/f Law [Zhou, ICCP 2009]

- written by Changyin Zhou @ Columbia U, 2009'

## Set Parameters

Noise level = 0.005; Blur size = 7

## Read Image

## Prepare the prior matrix: 1/f law

For specific scenes, suggest to use related images to generate the prior matrix, A

## Circular Pattern

## Levin's Pattern, [Levin, Siggraph 2007].

Note, this pattern is designed for DFD

## Veeraraghavan's Pattern [Veeraraghavan, Siggraph 2008]

## Zhou's Patterns, [Zhou, ICCP 2009]

This is one of the optimized patterns in [Zhou, ICCP 2009]
