Hi, I'm a Matlab newbie and I desperately need your help. I need to enhance image by performing operations on its histogram. But how can I apply that changes to the image? It's easy to extract histogram form the image but how to transform histogram back into image after performing e.g. histogram smoothing?
No products are associated with this question.
I suppose you could maybe use the intlut() function. But why don't you tell us what you want to do and we can tell you the best way to achieve it? You can upload your image to tinypic.com.
Thanks for the answer.
I need to implement a Generalized Histogram Equalization algorithm. The method is described in the following article (click to open/download a PDF file)
I'm stuck at the point where I have to remove the noise from histogram. I can do it e.g. with the medfilt1() method. It works fine for the histogram but what about the image? I need to change the image too. Is there any way to recreate the image based on the new histogram?
