Photo Pixelation Algorithm
user
Are there any reference or text I can read up on regarding the logic
and algo to pixelate a JPEG graphic?
Not necessary C code; but more or rather the algorithm flow of how it
should be done.
Please advise.
Many Thanks

If by "pixelate" you mean the effect usually used to obstruct faces
and genitalia, the algorithm is too obvious to reference.

No. I wish to pixleate the whole picture.
This is the first time I'm getting into graphics. It is total foreign
to me.
Perhaps you would give me some pointers?
Thanks

Calculate a single color for each NxN block of pixels of the target
image, by averaging the colors of the NxN pixels of the source image.

More generally: REDUCE the resolution of the original image by ANY
method, and then INCREASE the resolution of the image by "sample-and-hold".
