The main addition is the 3D curvelet transform in C++, available in three different implementations: in-core, out-of-core and fully MPI-based parallel. - Uploaded the report '3D Discrete Curvelet Transform'. - Corrected two bugs in the C++ implementation, related to array sizes for rectangular images. Thanks to Colin Russell and Jean-Francois Paradis for pointing this out. The online user's guide, curvelab.pdf, has also been updated.

We also corrected a slight inaccuracy in computing the thresholds in a denoise demo (thanks to Gilles Hennenfent for pointing this out). The new version is CurveLab 2.0.1. Two sister webpages were recently created, and they should be of interest to this email list: - http://www.l1-magic.org: "L1-MAGIC is a collection of MATLAB routines for solving the convex optimization programs central to compressive sampling." Compressive sampling (aka compressed sensing) is a method to recover sparse data from what appears to be very incomplete measurements. - http://www.chirplab.org: "ChirpLab is a collection of MATLAB routines for the detection of highly oscillatory and nonstationary signals---also known as chirps---from very noisy data." ChirpLab is based on wave snippets called chirplets. We welcome any comment related to the CurveLab toolbox. Also, feel free to make this email list more lively by submitting paper annoucements related to curvelets, etc. Yours, Laurent and Lexing From laurent@math.Stanford.EDU Fri Jan 26 03:08:19 2007 Return-Path: X-Original-To: curvelab-list@acm.caltech.edu Delivered-To: curvelab-list@acm.caltech.edu Received: from localhost (localhost [127.0.0.1]) by mail.acm.caltech.edu (Postfix) with ESMTP id EC9A1C00F0 for ; Fri, 26 Jan 2007 03:08:18 -0800 (PST) Received: from mail.acm.caltech.edu ([127.0.0.1]) by localhost (euler.acm.caltech.edu [127.0.0.1]) (amavisd-new, port 10024) with LMTP id 26986-01-2 for ; Fri, 26 Jan 2007 03:08:11 -0800 (PST) Received: from smtp1.stanford.edu (smtp1.Stanford.EDU [171.67.22.28]) by mail.acm.caltech.edu (Postfix) with ESMTP id 1A7C1C00E8 for ; Fri, 26 Jan 2007 03:08:11 -0800 (PST) Received: from smtp1.stanford.edu (localhost.localdomain [127.0.0.1]) by localhost (Postfix) with SMTP id 023F44C0D4 for ; Fri, 26 Jan 2007 03:08:11 -0800 (PST) Received: from math.Stanford.EDU (math.Stanford.EDU [171.64.38.20]) by smtp1.stanford.edu (Postfix) with ESMTP id DEB2A4C0CA for ; Fri, 26 Jan 2007 03:08:10 -0800 (PST) Received: from localhost.stanford.edu ([127.0.0.1] helo=math.Stanford.EDU) by math.Stanford.EDU with esmtp (Exim 4.62) (envelope-from ) id 1HAOwD-0000cY-O0 for curvelab-list@acm.caltech.edu; Fri, 26 Jan 2007 03:08:10 -0800 Received: from localhost (laurent@localhost)l0QB88U6002384 for ; Fri, 26 Jan 2007 03:08:09 -0800 Date: Fri, 26 Jan 2007 03:08:08 -0800 (PST) From: Laurent Demanet To: curvelab-list@acm.caltech.edu Message-ID: MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII; format=flowed X-Scan-Signature: 980022258218d8e0da9e8fd80fb6777b X-Virus-Scanned: by amavisd-new at mail.acm.caltech.edu X-Spam-Status: No, hits=-2.6 tagged_above=-100000.0 required=3.9 tests=AWL, BAYES_00 X-Spam-Level: X-Mailman-Approved-At: Fri, 26 Jan 2007 03:09:34 -0800 Subject: [curvelab-list] Python wrapper and Curvelab 2.0.2 X-BeenThere: curvelab-list@acm.caltech.edu X-Mailman-Version: 2.1.1 Precedence: list List-Id: List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Fri, 26 Jan 2007 11:08:19 -0000 Dear Curvelab users, Gilles Hennenfent and Darren Thomson from UBC wrote a Python wrapper for Curvelab, called PyCurvelab. They kindly agreed to make it available to us. To use the Python wrapper, (1) Go to http://www.curvelet.org and upgrade to Curvelab 2.0.2. We had to change a few lines in the 2.0.1 code to make it compatible with the wrapper. You don't need to upgrade if you won't be using the wrapper. The new release is backward compatible. (2) The weblink to PyCurvelab is listed on the download page of curvelet.org. Thank you Gilles and Darren. Also, please don't hesitate to use the curvelab-list if you have curvelet-related preprints you wish to share with the community---just send an email to curvelab-list at acm dot caltech dot edu.

See http://egl.beg.utexas.edu/rsflog/index.php?/archives/126-Curvelet- transform.html where you can also see an image denoising experiment. Madagascar is an up-and-coming integrated environment for anyone interested in reproducible research: "According to its website (http://rsf.sourceforge.net/), Madagascar (formerly known as RSF) is an open-source software package for geophysical data processing or, more generally, for reproducible numerical experiments. Its mission is to provide * a convenient and powerful environment * a convenient technology transfer tool for researchers working with digital image and data processing. The machinery is written using Python, SCons, and other tools but the actual computation is typically done in C/C++/Fortran although Python, Matlab and Mathematica can be employed using APIs provided by Madagascar.More details is available on Madagascar website athttp://rsf.sourceforge.net/. There is also a Madagascar overview presentation (http://rsf.sourceforge.net/rsf_overview.pdf) and a conference extended abstract (http://slim.eos.ubc.ca/Publications/Public/Conferences/ICASSP/2007/fomel07icassp.pdf) that may be of special interest for prospective users."

We have included a version of the curvelet transform that handles image boundaries by mirror extension instead of periodization, at a computational complexity comparable to the standard FDCT. The result is that boundary curvelets are now reflected back into the image, instead of being wrapped around by periodicity, in the spirit of wavelets on intervals. Switching to the new variant may improve sparsity in cases where the image presents strong contrast discontinuities across periodized edges. A new paper explains the construction of ME curvelets. The Matlab files for the new variant are in the directory mecv/. The toolbox can be downloaded from http://www.curvelet.org A new version of the wave atom transform for mirror-extended images is also available. Papers and software on wave atoms are available at the new webpage http://www.waveatom.org Enjoy, and please report bugs/feedback by email! Laurent Demanet and Lexing Ying.

Sparco is a suite of problems for testing and benchmarking algorithms for sparse signal reconstruction. It is also an environment for creating new test problems, and a suite of standard linear operators is provided (curvelet transform is one of them) from which new problems can be assembled.

My thesis is about synthesis imaging in astronomy. A few weeks ago, I discovered the curvelet transform and believed its application to the images I am working with could be very interesting and fruitful. So I decided to download the CurveLab software and installed in my laptop. Now, I am trying to understand the concepts and also trying to apply the curvelets to my problem. I read the paper "Fast discret Curvelets transforms", but there are many things that are still confused for me, many of them avoid me to use the CurveLab soft in practice. Excuse me if the following questions are a little trivials but I prefer to ask before going on with the work with the concepts/theory unclear. Now I am using the wrapping curvelet transform. 1º) When I obtain the coefficients 'c' from an image, I am supposed to access them by c[s][w](i,j), where 's' is the scale, 'w' the wedge and I guess (i,j) is the position or sample in that wedge. Suppose that I would like to create a new image with all the curves detected. How can I do this? I mean, Do I need to create 's' images, one for each scale? 2º) To create that image from the coefficients 'c', do I only have to arrange them in a 2-D matrix? I mean, if I have an original image Im, that it is a matrix of pixels of dimension N1xN2, from where I obtain coefficients c[s][w](i,j). For obtaining a curve image, is it enough to put in order the coefficients in a 2-D matrix N1xN2 (or 's' 2-D matrix)? or are necessary intermediate operations? 3º) How can I decide the width of the curves to be detected? Is this the scale? Well, I apologize again because I am sure the questions seem sillies, but believe me, from outside and facing the problem for the first time everything is a little confusing. So I prefer going step by step. Thank you for your help and looking forward to hearing from somebody :-) Roberto.
