I tried to convert a 48*48 gray image into pixels values, now i tried to convert it back into gray image, but the converted image is not showing properly, it show the upper portion of face below and below portion above.
my code is:
X = importdata('i2.txt');
d = reshape( uint8(X), 48, 48);
better_d = d([40:end,1:39],[25:end, 1:24]).';
