An image whose autocorrelation function is of the form of Eq. (8.2-49) with ρh = 0 is to be DPCM coded using a second-order predictor.

(a) Form the autocorrelation matrix R and vector r.

(b) Find the optimal prediction coefficients.

---

(c) Compute the variance of the prediction error that would result from using the optimal coefficients.
