Steve on Image Processing

April 23rd, 2010

Earlier this week I posted some relative speed improvement charts for some functions in the Image Processing Toolbox that got faster in R2010a.

Below are some more charts. I've included applylut, bwulterode, ifanbeam, imclearborder, imdilate, imerode, medfilt2, rangefilt, and stdfilt.

There are other functions that have gotten faster in the last couple of releases, including bwpack, bwselect, cornermetric, decorrstretch, edge, imclose, imopen, imextendedmax, imfill, imhmax, imimposemin, improfile, imreconstruct, imrotate, and imtransform.

   Those are great results.
   Yet, the dream is running those functions on the GPU.

   I agree, Mathworks should buy Accelereyes and incorporate Jacket as a standard toolbox. That would make MATLAB much more competitive. GPU computing is here to stay.

   I also agree.

   I have, however, heard rumours that we should see something in a not too distant release.
