March 2000 Newsletter Image Processing Special Interest Group http://image.nih.gov ------------------------------------------------------------- NEW IPSIG RESOURCE: The image processing SIG is starting a web page to list all available image processing software available to NIH researchers. This month we will concentrate on general image processing packages. Next we'll do registration, segmentation, visualization, etc. You can see our current list at (temporary location): http://www-ldrr.cc.nih.gov/staff/ostuni/soft_res/nih_soft_resource.html I am doing this in my free time so if anyone can help me fill in the blanks or correct errors please send email to me. Also, if anyone knows of any general image processing package besides the ones included, please let me know. -John (ostuni@helix.nih.gov) ------------------------------------------------------------- Next Presentation: Date: 3/16 Time: 11:00-12:30 Place: LDRR conference room Speaker: John Ostuni Abstract: This presentation is for anyone who uses C or C++ to write image processing software. This presentation will be in two parts in order to present two different C++ classes. 1. Oimage -- for working with 1, 2, 3 or 4D images. Handles all memory allocation and io (files and/or sockets). Allows you to go back and forth between objects and image arrays so you won't have to change your current source code. Also, many handy features too numerous to mention here, but can be found at the Oimage web site: (http://www-ldrr.cc.nih.gov/ostuni/oimage/oimage.html) 2. Otrans -- for working with rigid body transformations. Allows you to easily set/get rotations, translations and center of rotation. Different modes allow for different rotation orders and fixed/floating rotation axis. Can easily go back and forth between object and 4x4 transformation array so you won't have to change current source code. Many handy features such as file io and basic mathematics. For more information, see: (http://www-ldrr.cc.nih.gov/ostuni/oimage/oimage.html) ------------------------------------------------------------- INFORMATION REQUEST: I'm interested in seeing what pricing different labs within the NIH have paid for access to Matlab. I was somewhat shocked to find out that the Mathworks wants us to pay a minimum of $2,800 (for one Unix license) for just the base Matlab software, and $about 1,350.0 per toolkit (image processing, statistics etc). At my old school, a flat fee of $160.00/CPU gave yearly access to almost the entire Matlab product line. This would require almost $50K if the price list was strictly adhered to. Since most users in research labs at the NIH would seem to fall into the academic definition. I wanted to see if others have found a way around this problem. I'm trying (so far unsuccesfully) to lobby Mathworks to reconsider. I'm also starting to understand why so many imaging labs use IDL ... So, if you do have any direct experience with procuring Matlab at the NIH, please send me an email with relevant details (e.g. platform, product/toolboxes and price). Anectdotes and suggestions are welcome as well.

Introduction to Image Processing I March 13, 15, 17, 20, 21, 24 2. Introduction to Image Processing II April 3, 5, 7 3. MEDx - Unix-Based Medical Image Data Analysis Introduction to MEDx/Image Calculator: March 3 Region of Interest Analysis: March 10 AIR and Shadow Transform: March 31 For the complete course list, more information and/or to sign up, go to: http://training.cit.nih.gov and look under "Seminars for Scientists" NOTE: You must sign up for these courses through CIT ------------------------------------------------------------- MEDx INFORMATION: Reza Momenan has informed us that there is a new Medx script depository web page: (http://www-medx.cc.nih.gov/MEDX_WWW/CxTCL/cxmainmenu.html) ------------------------------------------------------------- PRESENTERS WANTED: We are always looking for people to present. It is a great way to get feedback on your work and contribute to the group at the same time. Presentations can be on: *) your current image processing work *) any published image processing journal paper *) any type of tutorial on an image processing concept *) any type of tutorial on image processing software *) etc If you wish to present or would like to find out more, email John Ostuni(ostuni@helix.nih.gov) or Benes Trus(trus@helix.nih.gov). ------------------------------------------------------------- PLEASE UPDATE! As most of you know, there is a database of all image processing researchers at our web site (http://image.nih.gov/Research.html). This site is viewed by many people both inside and outside of NIH. In fact, many people here have gotten their jobs by using this database to find the right people to contact. When you get a chance, please look at your entry and update if it is out of date (http://image.nih.gov/About.html). If you don't have an entry and are doing image processing on the NIH campus please submit an entry through our website. ------------------------------------------------------------- NEWSLETTER INFORMATION: If you would like to include something in next months newsletter, please send email to ipnews@image.nih.gov.
