I am working in a project and I do not know how to get the BER between my orignal image and the one received.

so basically If do this

A=imread('m.jpg)
B=imread('m.jpg)
(n,R)=biterr(a,b)

I should get zero ber but this method is not working for me and i am getting an error message. Can somebody help please.

Thanks

Actually biterr() *is* a MATLAB function

You need to tell us what the error message is.

Please also tell us class(A), class(B), size(A), size(B)

??? Error using ==> de2bi at 159

Specified number of columns must be scalar.

Error in ==> biterr>toBinary at 299

b = de2bi(a(:), num_bits);

Error in ==> biterr at 216

a2 = toBinary(a, num_bits);

Error in ==> untitled2 at 6

[n,R]=biterr(a,b);

I do not have the first three commands in my code I do not know where matlab brought them from. and the pictures are same size because they are the same <540*720*3 unit8>. Please help me if you know any other way to find bit error rate for 2 similar jpg images.
