How to get the (2,2) pixel of every (4,4) block. I know how to get the (0,0) for every (4,4). Sample code as below
import numpy as np
image = np.arange(12*8).reshape(12,8)
print(image)
image2 = image2 = image[::4, ::4]
print(image2)
Output:
[[ 0 1 2 3 4 5 6 7]
[ 8 9 10 11 12 13 14 15]
[16 17 18 19 20 21 22 23]
[24 25 26 27 28 29 30 31]
[32 33 34 35 36 37 38 39]
[40 41 42 43 44 45 46 47]
[48 49 50 51 52 53 54 55]
[56 57 58 59 60 61 62 63]
[64 65 66 67 68 69 70 71]
[72 73 74 75 76 77 78 79]
[80 81 82 83 84 85 86 87]
[88 89 90 91 92 93 94 95]]
[[ 0 4]
[32 36]
[64 68]]
I would like to see
[[ 9 13]
[41 45]
[73 77]]
