An image is a matrix (actually three matrices, or RGB color values). I read in an image, 352x192, and computed the SVD of the three color bands. I then reconstructed the image in three ways:

Here are the results:

Original image, using all 192 outer products from the SVD Compressed using 90 outer products -- it's almost the original -- can you find any differences? Compressed using only 30 outer products -- quite "lossy"
