WebJun 17, 2016 · JPEG compression is based on the following 2 observations: Observation #1: Human eyes don’t see color (chrominance) quite as well as we do brightness (luminance). Observation #2: Human eyes can’t distinguish high frequency changes in image intensity. Step 1: Convert RGB to YCbCr color space WebImage compression works by transforming the 2d discrete pixels into a frequency spectrum with Fourier transformation, then it removes the frequencies that the human eye can't see are missing. Decompression is the fourrier transform invert, and since some pixels are not expressed through frequencies anymore, some details are lost.
