Problem

Compute the mean absolute error between two same-shaped grayscale images.

For every pixel accumulate abs(a - b) and divide by the number of pixels, rounding the result to 4 decimal places.

case 1

in: [[[1,2],[3,4]],[[1,1],[3,6]]]

case 2

in: [[[10,20]],[[20,10]]]

expected: 10

case 3

in: [[[1,2],[3,4]],[[1,2],[3,4]]]
