I am using Matlab 7.1. It works well, no issue.

Takes a long time to run and the "Progress indicators" are not good. It says 4 times that need to wait and then you are Done! but actually this is only within a loop that gets executed 4 times. Then there's more to do after that, so the messages are very deceptive. Then it doesn't even display the original image or the 4 result images despite the fact that it's not a general purpose routine that returns an image - it's a script with input and output filenames hard-coded into it. Come on, at least you could display the images for us! When I did display them (myself) the results weren't even that good, which may be more the fault of the algorithm than the programmer. And there are several misspellings and so-so documentation. Overall, it needs work if it's going to be a nice demo program (for example a way to pick your own input image, etc.).

I am doing my project on MRI brain image segmentation using ANT colony optimisation. Can anyone help me to start?

[lavanya ananthan]

Is this method is applicable for medical images?

what is the problem will it work for x ray images
