I need to estimate the IMFs of EMD of given image. I use PSO to estimate the IMFs of EMD. I don't have much knowlegde about PSO. Anybody help me in PSO programming in Matlab.

I need practical view of PSO like bio intelligence algorithm applications in image segmentation. I'm naive in PSO like concepts. I don't know how to apply it to image segmentation concepts.

I'm guiding a student project to handle texture smoothing, hence I need an alternative to PCG solver which is as existing solver... If you have Matlab code available, could you share it with me?

I intend to use PCA for image compression. But I don't know how many PC's can be used for the maximum energy of image to be retained with maximum compression? I faced the same problem in SVD also.
