Chapter 11.2, Problem 4E

Use the quantization matrix $Q=\left[\begin{array}{cc}10& 20\\ 20& 100\end{array}\right]$ to quantize the matrices that follow. State the quantized matrix, the (lossy) dequantized matrix, and the matrix of quantization errors.

$\begin{array}{l}\text{a}\text{. }\left[\begin{array}{cc}24& 24\\ 24& 24\end{array}\right]\\ \text{b}\text{. }\left[\begin{array}{cc}32& 28\\ 28& 45\end{array}\right]\\ \text{c}\text{. }\left[\begin{array}{cc}54& 54\\ 54& 54\end{array}\right]\end{array}$
