Executive Summary

The proliferation of pictures and videos in the Internet is imposing heavy demands on mobile data networks. This demand is expected to grow rapidly and a one-fit-all solution is unforeseeable.

The intuition is that humans exhibit unequal interest towards different parts of content, and parts that are less important may be traded off for price/performance benefits. For instance, a picture with the Statue of Liberty against a blue sky may be partitioned into two categories - the semantically important statue, and the less important blue sky.
