@axiommotion: JPEG compression, explained: every 8×8 block of a photo is a weighted sum of 64 cosine patterns (the DCT). The transform loses nothing — the rounding after it is what shrinks the file. One real block, rebuilt exactly, then quantized: 44 of 64 coefficients drop to zero and your eye barely notices. #math #jpeg #imagecompression #stem #manim
