14 Aug 2012 3D Slicer Slicer for exploring 3D images (grayscale, color or vectorial) through planar or 3D slices. Author: David Legland

This function offers the same capability available with expensive commercial software for CT / MR explotation.
It would be desirable to have an option to generate the histogramm of the voxels-luminosity (excluding the background voxels ) e.g. like : hist(Volume(good_voxels),nbins).
The valley of the histrogram can used for region-based volume segmentation.

09 Dec 2011 DCT and DST (+ inverse) in arbitrary dimension Discrete cosine/sine transforms and their inverses Author: Damien Garcia

these function when used in >resize3d< allow faster volume resizing of large volumes with less memory usage
10 Jun 2011 DGradient Gradient of arrays as fast C-Mex Author: Jan Simon

much faster than matlab gradient() !
19 Jul 2010 radon-iradon bijection issue TEST Test that shows Matlab's radon and iradon ERRONEOUS reconstruction on pixel-to-pixel position Author: Erik Rodrigo Valdes-Estrada

use gray levels rather than RGB and add the (gray) colorbars ...
use a better phantom ! (eg. one cross or a L or a more complex gray phantom rather than a BW)
use a larger phantom image.
in my view it is not a matlab bug ... just rounding behaviour relater to the limited size of your image...

19 Aug 2010 skeleton in 3D Distance transform oriented code for 3d skeletonization. Author: Gianni Schena David

the performance highly correlated to the tuning parameters, and also there is no mechanism applied to check the connectivity of the centrelines.

15 Oct 2009 skeleton in 3D Distance transform oriented code for 3d skeletonization. Author: Gianni Schena Ben

Both reference links are died. How about this program?? :(

Anyone know the idea on how to tune the parameter?

12 Aug 2009 skeleton in 3D Distance transform oriented code for 3d skeletonization. Author: Gianni Schena Roberts, Mokone

The code rejects fspecial3 function and I cant proceed from here.
