Hello friends,

I am trying to classify between 2 sets of images(for eg - class a and class b). I have a database of images(of both class a and b).the images are colour images.

i am trying to design a neural network to classify them.
how do i approach this problem? Pls suggest.

regards,

It depends on the images, but in general this is a hard problem, and you might need to register to study for a PhD at a university with a good record of work in image analysis. I guess this doesn't sound helpful, but I am entirely serious - image classification (using neural nets or other methods) is a very active research area, and you are likely need more guidance than you can get on a forum.

If you happen to have images that are relatively easy to classify, for example because they show particular objects with very different appearances, then it might not take so long. A crucial step is in working what measurements on the images you are going to present to the neural network. However, even with easy images, some work with textbooks, and with the documentation for the Image Processing and Neural Network toolboxes, will be needed as a start.

Hello Mr Young,

Is there any other simple classification method that you could suggest?

Regards
