• And now for something completely different

    Updated: 2012-04-11 01:00:40
    The following video spread up and down the MATLAB Math team's hallway like wildfire yesterday: http://www.youtube.com/watch?v=ywWBy6J5gz8 I said there was some room for improvement because I thought the last 20 seconds or so of the algorithm could be optimized away. However, math developer Bobby informed me that those last few dance steps are necessary to [...]

  • imzoneplate on the File Exchange

    Updated: 2012-04-10 01:45:46
    Last year I posted a few times about the "Jähne test pattern," something that readers then told me was called a zone plate. This is a radial sinusoid pattern with low frequency in the middle of the image and high frequency toward the edges: In my 02-Jul-2012 post, Filtering fun, I used the zone plate [...]

  • MATLAB R2012a

    Updated: 2012-04-03 01:00:28
    Some of my fellow MATLAB Central bloggers have already talked about the MATLAB R2012a release. Usually, I like to scan the release notes and pick out just a few things that particularly interest me. I encourage you to take a look at the release notes to see what else is there that might interest you. [...]

  • Image Processing and Computer Vision Updates in R2012a

    Updated: 2012-03-30 15:59:20
    MathWorks shipped R2012a right on schedule earlier this month. (Normally, the "a" release ships in March and the "b" release ships in September.) There's a lot to look at in the new release. Today I'll summarize the enhancements in the Image Processing Toolbox, the Computer Vision System Toolbox, and the Image Acquisition Toolbox. Image Processing [...]

  • Image inpainting using PDE techniques

    Updated: 2012-03-13 22:00:38
    This week I want to highlight a new article on mathworks.com called "Applying Modern PDE Techniques to Digital Image Restoration," by Carola-Bibiane Schönlieb of the University of Cambridge. Dr. Schönlieb describes PDE-based inpainting, or image interpolation, used to reconstruct missing parts of images. Her inpainting work began on a project to restore some 14th-century Viennese [...]
