• Faster morphological reconstruction in R2009b

    Updated: 2009-10-19 08:00:36
    We've been working for a while now to make Image Processing Toolbox functions run faster. The R2009b release notes mention several performance improvements. We've gotten some feedback, though, that our release notes are pretty vague about the improvements. I can't argue with that impression. [...]

  • Deploying Image Processing Toolbox apps in R2009b - we goofed

    Updated: 2009-10-12 08:00:38
    Ack! We discovered recently that we broke application deployment when using the MATLAB Compiler with Image Processing Toolbox functions in R2009b. The problem happens only on Windows and is caused by some missing shared libraries in the deployed application. If you use the R2009b MATLAB Compiler on Windows with the Image Processing Toolbox, please see our published [...]

  • MATLAB Virtual Conference on October 14

    Updated: 2009-10-05 08:00:08
    We're having a MATLAB "virtual conference" on October 14. There'll be presentations, live Q&A, roundtable discussions, chats, etc. It should be fun! I'm scheduled to do a talk on MATLAB indexing techniques for image processing. You can register any time on the event overview page. Be sure to check out the presentation schedule to see what might [...]

  • Many steps needed for some color-space conversions

    Updated: 2009-09-09 18:08:38
    It can take a lot of computational work sometimes to convert between color spaces. I was recently looking at the computational steps needed to convert between sRGB and a particular CMYK space known as US Web-coated SWOP, often just called CMYK SWOP. The Image Processing Toolbox ships with ICC profiles corresponding to each of these spaces. [...]
