This is a great little program. However, i also get problems for large loops:

??? No method 'createServer' with matching signature found for class 'ParforProgressMonitor'.

Error in ==> ParforProgMon>ParforProgMon.ParforProgMon at 48
                o.JavaBit = ParforProgressMonitor.createServer( s, n );

Hello all,

I'd appreciate it if you can drop a line about the performance of this script for your images, and any cases that you might encounter under which the performance drops down steeply or vice versa.

Or any other functionality you'd like to see. Thanks!

Works perfectly now!

The function seems useful.
I'd like to ask something, risking to look stupid: Is it correct to assume, that for getting the actual filter (to see how it looks, also I need to use the same filter on thousands of images), it is enough to choose I as a matrix consisting of ones?
Thanks in advance for the help.

This source code is desperately needed to continue my work. Thank you very much if you can send the code to jadebestcai@yahoo.com. Appreciated!

sir,
this excellent work done by you. but can please give detial description of this model i would like to know about the design and how did u make this model in detail in simulink becoz i am looking for ward this type of models in simulink hope u will reply soon to my email address:siddhu_venki2006@yahoo.co.in or in mathsworks only

Hello,
 wonderful work, there is a complete documentation?

m making a proj on iris recognition... n m facing probs... so plzz send ur iris recognition code as soon as possible on
shailagarg23@yahoo.com
plzzzzzzzzzzzz send it asap

thanku its agood work

its good work.. new innovation

nice details

John, Have not seen teh new submission yet. perhaps it takes the server a while to update?
Best, Joel

That's a very useful code. Can you please provide some references for the robust spline fit and the periodic condition options?

Thanks!

A bug in the code for odd dimensionality. Sorry about that. The repaired version has been submitted. With the repair made...

>> spheresegmentvolume([.5 1],3,1)/(4/3*pi)
ans =
      0.15625
>> spheresegmentvolume([0 2],1,2)
ans =
     2

If there is interest for a Windows version, I can easily port this code to use boost::interprocess. This would make it platform independent. Please respond if this is something you need.

I am struggling with something. I don't want to imply there is a bug in the code but there must be something I am not understanding:
 spheresegmentvolume([.5, 1],3,1) / (4/3*pi)
 0.34375

Should compute the ratio of the volume of the cap from 1/2 the radius vs the whole volume of the sphere in 3D. But a sktech shows pretty clearly there is no way that cap should be near 1/3 of the volume. What am I missing? Perhaps I am misinterpreting the input argument t?

Nafise, post your situation/goals, your images, and what you've tried to the newsgroup (http://www.mathworks.com/matlabcentral/newsreader/). From there people can help you.

ThX sean,
I did it, but it is not true, because my image has black regions, and it determines that part with zero pad part.
WHAT SHOULD i DO NOW?!

C Berry,

I'm not quite sure what you mean when you say it doesn't parse a minus sign; can you give a small example?

Thanks for your code.
I want to work with your code, but I have a problem with it.
In fact, my images are 2 blocks which don't have the same size, and I want to find the best place for small block in the big block.
Something that I got from your code is for your code 2 images have same size.
What should I do now, if I want to use your code for subpixel image registration?

Best regards,
Nafise

Jenn Risk: just use det(CovMatrix) for area/volume.

M ChC, Volkan Ozturk:
figure; handle(1)=error_ellipse(A); hold on; handle(2)=error_ellipse(B); handle(3)=error_ellipse(C); set(handle(2), 'color','r', 'linestyle',':'); set(handle(3), 'color','k', 'linestyle','--');

Reply to Bree:

Try reading with
  Pref.Str2Num = 'always';
  MyTree1=xml_read('test.xml',Pref);

Default Str2Num preference is 'smart' which does not try to convert strings with more than 10k characters. Occasionally the strings in XML can be VERY large, for example when you have Base64 encoded images in the file. In such cases regexp code I am using can be very slow.
