It seems that decreases error curve always has the same shape. Is there a name for this shape? I assume you could sample just a few points and have a good estimate of what the error will be for any truncation.

There are better ways to apply SVD to images than the way its usually taught

Meaningful decompositions have got to be my favorite subject in linear algebra, and SVD is the king of these. Another location this pops up is "eigenfaces", an early form of compression (and correlation) of images of faces.
