Question

You are given four images to represent as

$I_1 = \begin{bmatrix} 0 & 0 \\ 0 & 0 \end{bmatrix}, I_2 = \begin{bmatrix} 0 & 1 \\ 0 & 0 \end{bmatrix}$, $I_3 = \begin{bmatrix} 0 & 1 \\ 1 & 0 \end{bmatrix}, I_4 = \begin{bmatrix} 1 & 1 \\ 1 & 0 \end{bmatrix}$

The value of entropy is maximum for image

• A. $I_1$
• B. $I_2$
• C. $I_3$
• D. $I_4$

Answer 1

ans C

entropy of image represents the randomness in pixels. in I1 all pixels are same. entropy is 0.
in I3 2 pixels are same other 2 diff.
in i2 i4, 3 are same.
so most random is in I3
