I used 4 block encoding techniques to encode/decode image. I first added some noise to image, then encoded it, then applied filter to reduce noise and then decoded it. I did these steps in all 4 encoding techniques.
Now I want to compare those techniques to find out which one is better. I know that it can be done by ploting BER but I don't know how to do it.
Can you pls help me with this?

From my understanding you want to know how to user BER to compare two images. Here is an example :
A=imread('m.jpg)
B=imread('m.jpg)
(n,R)=biterr(a,b)
You can also determine the theoretical BER curve by using the berawgn function. Refer Bit Error Rate Computation for more information.

Thankyou I wanted to create a BER curve. I have one question. In berawgn, what should be my EbNo?
Sorry if this is a naive question. Should I convert my final decoded image to vector for EbN0?
