Hello,
I would like to average the bit values in the 8x8 cells of a JPEG-coded
photograph:
If the original is, say, 1024 x 768, then I would like to downsize it to
128 x 96 pixels, each of the pixels representing the average value of
one of the original 8x8 JPEG cells.
Can this be achieved by ImageMagick?
And if so: could I also determine the variance in the 8x8 cells?
Greetings from Germany
Wolfgang Hugemann
