Solve the following problem:
(a) DPCM-encode the Sinan, Elif, and bookshelf 1 images using a two-tap predictor and a four-level quantizer followed by a Huffman coder.
(b) Repeat using a five-level quantizer. Compute the SNR and rate (in bits per pixel) for each case.
(c) Compare the rate distortion performances with the one-tap case.
(d) Repeat using a five-level quantizer. Compute the SNR for each case, and compare the rate distortion performances using a one-tap and two-tap predictor.
