27 Mar 2013 Fast Loop mesh subdivision Subdivide a surface mesh, using Loop subdivision. Boundary- and shape-maintaining. Author: Dylan Muir

Hi Dun,

I would be happy to include your improvements if you send them to me; my email address is my last name at hifo.uzh.ch

Regards,
Dylan
14 Feb 2013 Circular Statistics Toolbox (Directional Statistics) Compute descriptive and inferential statistics for circular or directional data. Author: Philipp Berens

Great toolbox. I was wondering if it is possible to have more accurate p-value estimates in the Kuiper test?

29 Feb 2012 Fast Loop mesh subdivision Subdivide a surface mesh, using Loop subdivision. Boundary- and shape-maintaining. Author: Dylan Muir

Hi Jaroslaw,

The Loop subdivision algorithm provides mesh smoothing and refinement:

Certainly the original mesh points are not preserved. That's not how the algorithm works.

27 Feb 2012 Fast Alpha Hulls (parfor enabled) Compute the alpha hulls (exterior and interior) of a set of points. Author: Dylan Muir

Hi Borc,

Your point cloud contains many points and triangles that are co-planar; this causes the determination of whether or not the triangles are on the alpha surface to perform badly. If you add a tiny jitter to each point:

cloud = cloud + (rand(size(cloud))-0.5)*0.001;

then everything works as it should. If you have a suggestion for sorting out this corner case, I'd love to hear it.

Best regards,
Dylan.

26 Apr 2013 Import ImageJ ROIs Read ROIs and ROI sets saved from ImageJ into MATLAB, without java. Author: Dylan Muir Zachary

Nevermind! Figured out the problem. I altered slightly how the transformation was done in respect to vnRectBounds and it seems to work flawlessly now!

Thanks for the script!

Update:
After adding a few tricks, it takes only 0.861 seconds from 223 triangles to 228352 triangles (5x subdivisions).

Making use of the Matlab embedded data structure: TriRep could make this a lot faster. This function took 206.36 seconds subdividing 122 triangles to 124928 triangles (5 times subdivision). I did it in 2.2 seconds with TriRep.
14 Mar 2013 Import ImageJ ROIs Read ROIs and ROI sets saved from ImageJ into MATLAB, without java. Author: Dylan Muir soup, lobster

Can you let me know how I can access the xy coordinates of the roi so I can draw it?
when I say
[roilist] = ReadImageJROI(roiDirectoryCell)

I get a struct within a cell. The only information i can find to reconstruct the roi is vnRectBounds, and I don't understand how to make use of it.
The roi I'm trying to draw is of type 'oval'. could you please explain this in some more detail?
thanks!
