Hello Marikhs,

Please, note that deleting the DPSO and FODPSO is irrelevant. As long as you choose 'pso' as method it won't influence at all.

The example given in the header should work on any image:
Iout = segmentation(I,4,'pso')

If you're having a problem working with a specific image just send it to me to micaelcouceiro@gmail.com and I'll try to check what's going on.

Regards.

Dear Timo,

I haven't heard about this problem before although I can understand it. It seems that the round function inside drmex.c is conflicting with the round function from matlab or another user-created function you may have.
Before we try to think about a possible solution, please download the following version of MRSim:

http://www2.isr.uc.pt/~micaelcouceiro/media/MRSim_vbeta.zip

This version already has the compiled files which may or may not work with your system. Try to run simview/simedit without compiling the files from this new version.

Hello,

One of the references is cited on the description of the matlab file:

Pedram Ghamisi, Micael S. Couceiro, Jón Atli Benediktsson & Nuno M.F. Ferreira. “An Efficient Method for Segmentation of Images Based on Fractional Calculus and Natural Selection”, Expert Systems with Applications, Elsevier, 2012.

An alternative would be:

Pedram Ghamisi, Micael S. Couceiro, Fernando M. L. Martins and Jón Atli Benediktsson. “Multilevel Image Segmentation Based on Fractional-Order Darwinian Particle Swarm Optimization”, IEEE Transactions on Geoscience and Remote Sensing, 99, pp. 1-13, 2013.

If you have any problem accessing those e-mail me to micaelcouceiro@gmail.com and I'll send you my personal copy.

Regards.

Dear Marikhs Roses,
Can you please tell me more details about what you may need? Did you tried to use this function on your case study first?
Regards

Dear Gousal,

The help (header of the script) is pretty much straightforward. But, basically, you simply have to open an image using MatLab as, for instance:

I=imread('teste.bmp');

Then call the segmentation function as, for instance:

Iout = segmentation(I,4,'pso')

This will result in a image Iout with the same dimensions than I but with only 4 different levels.

Kind regards

Hi, I am trying to run the demo and m getting the following error. Also I am not getting the 'run' option in the simulation window..

Undefined function 'prmex' for input arguments of type 'double'.

Error in simrobot/putrob (line 59)
if

== -1

Error in simviewcb (line 425)
list1(i) = putrob(list1(i),history(1,1:2),matrix);

Error in simviewcb (line 385)

What does that mean??

Respected Sir,
I already try your coding and it give me a good result. I need your help,how to choose the level for the PSO as 2.
so can u please help me. Thank you
