pso is nature inspired optimization technique based on bird flock or fish school behaviour.

In order to use PSO, you need a cost function, a measure of how good any particular possibility is, with lower values being better. What would be your cost function for segmentation? What would the inputs look like, and how can you tell how good the choice is?

Sir, I am working with finding threshold value for image using pso in matlab. I am not able to do that. I will be very thankful to you if u help me. I don't know exactly from where should i start.

At what point do you want to use PSO? To produce an image that you can threshold, or to use on an existing image in the threshold determination algorithm? If it's the latter, why not just use traditional threshold determination algorithms?

I have used otsu method and got a value of threshold on the basis of which i segmented my image. But i want to calculate threshold using pso. But to write its code in matlab is very difficult for me. I need u to please help me in the code.

Sir, graythresh function is used to calculate threhsold of image using otsu method. I have understood the code behind that function.But now I am unable to use pso algorithm in finding value of threshold for my test images. I need your help sir

I have not heard of any method using PSO to compute a threshold. Why do you think there is? Why is it better than any other method? Have you seen my interactive thresholding method?

What sort of help do you need? You didn't say. I don't have any ant colony code and I can't write a turnkey application for you. There is ACO code in the File Exchange.

Try to adapt one of those.
