Dataset Mean Color

Problem

Compute the mean color of a dataset of RGB images.

Average each channel over every pixel of every image and return the three means rounded to 4 decimal places.

Hint

Count pixels across the whole dataset, not per image.

case 1

in: [[[[[100,0,50]]],[[[200,100,250]]]]]

expected: [150,50,150]

case 2

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

expected: [127.5,127.5,127.5]

case 3

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

expected: [0,0,0]
