Question

Given a picture with just 2 pixels and 3 potential values for every pixel, what is the
quantity of conceivable picture histograms that can be shaped?​

Answer 1

Answer:

dftrd

Explanation:

m...m.m..m..mmm.m.

Answer 2

9 Images and 6 histograms.

Explanation:

The pixel values in the images would be:

(0, 0)

(0, 1)

(0, 2)

(1, 0)

(1 1)

(1, 2)

(2, 0)

(2, 1)

(2, 2)

Histograms for pixel values will be discrete:

(0, 0)

(0, 1) and (1, 0)

(0, 2) and (2, 0)

(1 1)

(1, 2) and (2, 1)

(2, 2)

Each pixel can have any of 3 possible values, and so there are 3×3=9 possible images. On the other hand, since order does not matter for histograms, there are only 6 possible different histograms, for example, assuming possible values 0, 1, 2, images 01 and 10 have the same histogram.
