Dataset Std Color

Problem

Compute the per-channel color standard deviation of a dataset of RGB images.

Use the population standard deviation over every pixel of every image and return the three values rounded to 4 decimal places.

case 1

in: [[[[[0,0,0],[255,255,255]]]]]

expected: [127.5,127.5,127.5]

case 2

in: [[[[[0,10,20]],[[10,20,30]]]]]

expected: [5,5,5]

case 3

in: [[[[[7,7,7]]],[[[7,7,7]]]]]

expected: [0,0,0]
