Matlab code could run,but the speed is ont fast.Maybe there are double for-loop in code.

A couple of points:
1) It does not interpolate. This is okay for translations with this script because all translations are in integer quantities in each axis. But the lack of interpolations mean rotations will produce some unexpected artefacts.
2) You have to go into the code to add a fill value for shifted in data.
3) SLoooooooooooow!
4) No documentation, so you have to torture yourself with mental tetris + trial and error to figure out how axes are set in this script

If you want to do 3d rigid transformations, your best bet is to use the Image Processing Toolbox's imwarp function, after specifying the centroid/frame origin. It provides functionality for interpolation (very important!). Also take note of what value it inserts to shifted in data when translation happens. Imwarp takes care of the fill values too. I know, MATLAB charges big bucks for it, but they have a perfect, efficient, and well documented implementation in imwarp. Yes, it's also a little bit more work to figure out imwarp - no pain no gain.

I gave the script a 1 star rating. That star is for participation!

Yulius Harjoseputro

hi, i'm very interested about your program. I have download example code in your program but I get error like this :

Error in gradient (line 49)
[err,f,ndim,loc,rflag] = parse_inputs(f,varargin);

Output argument "varargout{2}" (and maybe others) not assigned during call to "C:\Program
Files\MATLAB\R2013a\toolbox\matlab\datafun\gradient.m>gradient".

Error in fpdepyou (line 20)
[Ix,Iy]=gradient(I1);

Can you help me please to fix this error?

The function is badly written. There are unused variables lying around, and the 2 for loops could be removed in favor of the usual Matlab tricks for computational efficiency.
The results are not that visually satisfying either - the color temperature is definitely off on some of the images I tried this function on.

Is it possible to store the logical array of each segment into a 3 dimensional array? I need to be able to call up the logical array representation of each segment.
