we have a matrix of dimension (65536X12) how can we find covariance of such a matrix which is not a square matrix

As was true of your previous post, your question is not clear. Do you have 65536 measurements each of 12 variables, or the reverse? If the former, then
cov(M)
(where M is your matrix) will give you a 12 x 12 covariance matrix for the variables. If the latter,
cov(M')

I don't suppose it's a coincidence that 65536 = 256^2. Are you trying to correlate each pixel with each other pixel?
