From: Vinod on 3 Mar 2010 23:59 Hello Friends, What is normalization(for image and a signal)? What I understand is for eg a signal x = [1 3 5 7 9 11]. 1) Is it norm_x = x/sum(x) or norm_x = x/sum(|x|). If it is abs values of x, why is it so? 2) In case of images how do I approach this task? Should I first take the normalization of rows and then follow it with that of columns? Or would normalization of rows serve my purpose? Is it then necessary to move into column processing? Would it involve dividing of each pixel by the sum of the row(relevant0 or by the whole image sum? 3) What is the need/use and application of normalization. What data can I get from image normalization? Regards, Vinod Karuvat. |
