Consider the conditional entropy and mutual information for the binary symmetric channel. The input source has alphabet $X=\{0,1\}$ and associated probabilities ${\dfrac{1}{2}, \dfrac{1}{2}}$. The channel matrix is $\begin{pmatrix} 1p & p \\ p & 1p \end{pmatrix}$ wgere p is the ... given by: $1$ $p \log(p)(1p) \log(1p)$ $1+p \log(p)+(1p) \log(1p)$ $0$

Given a simple image of size $10 \times 10$ whose histogram models the symbol probabilities and is given by $P_{1}$ $P_{2}$ $P_{3}$ $P_{4}$ a b c d The first order estimate of image entropy is maximum when $a = 0, b = 0, c = 0, d = 1$ $a=\frac{1}{2}, b=\frac{1}{2}, c=0, d=0$ ... $a=\frac{1}{4}, b=\frac{1}{4}, c=\frac{1}{4}, d=\frac{1}{4}$
