New compression algorithms are always interesting because they reveal a new way of describing a photograph in a succinct way. The overlap between image compression and image searching is surprisingly high because the same techniques are used to derive the most important part of the picture data. Even if a new compression isn't ideal for image transmission, it is pretty much always a new avenue to look at for image matching/searching.

Coming from the other side, corners and edges are great ways to describe an image when doing process. It's a natural step to use this data for compression, which is what the authors have done here.

I understood the pixels for compression were chosen randomly, not by how much they define the main features of the picture. Or you meant the selected pixels are assumed to be defining features when reconstructing the image?
