We looked at JPEG images stored at different "quality" in the lecture. These images show an example of how well the JPEG compression process works. All images are the same size (in number of pixels); the original was taken by a typical consumer 5-megapixel camera.
High quality (1.0) JPEG file, 3.47 MBytes
Good quality (0.8) JPEG file, 0.833 MBytes
Medium quality (0.6) JPEG file, 0.5 MBytes
Low quality (0.4) JPEG file, 0.37 MBytes
Poor quality (0.2) JPEG file, 0.2 MBytes
