I have done for single gray image (RGB Just having three plane), or you can easily incorparates the same.
image_test=magic(5) % Just for example 5x5 gray image
data1=sort(image_test(:));
final_image=reshape(data1,[5 5])
Command Window:
image_test=
17 24 1 8 15
23 5 7 14 16
4 6 13 20 22
10 12 19 21 3
11 18 25 2 9
final_image =
1 6 11 16 21
2 7 12 17 22
3 8 13 18 23
4 9 14 19 24
5 10 15 20 25
*If you have look for RGB images, just extract the all three plane and do the same and later concanate results again to 3 plane image.
Hope it Helps!
