  1. Lecture 19 Figures from Gonzalez and Woods, Digital Image Processing, Second Edition, 2002.

  2. Lossy Compression • Error free compression loses no information, it just looks for a more optimal way to store it. Compression is at best about 3-to-1. • Lossy compression imposes a (tolerable) distortion to store the image more efficiently. We are actually giving up something. • Compression can be 100-to-1 and indistinguishable from originals at 10-to-1 or even 50-to-1.
