4. As we discussed in class, entropy can be viewed as measure of information. It is thus perhaps not surprising that entropy can be defined for pure data, such as neural spike trains, MRI images, streaming audio/video, etc. For a 256-grayscale (8-bit) image with N pixels, the entropy can be defined as: where p, is the fraction of pixels with grayscale intensity equal to i. minimum entropy. maximum entropy. S--pInp, A) What is the minimum possible image entropy? Give an example of an image that has B) What is the maximum possible image entropy? Give an example of an image that has

Explanation / Answer

Entropy means disorderness, when atoms/molecules are moment more in the gaseous state, in liquid state somewhat disorderness decresased ,in solid state disorderness more decreases, in nature disorderness increases that is spontaneous for nature,and energy decreases generally that is spontaneous .

Delta S = +ve (spontaneous )

Delta G = -ve ( spontaneous )
