­Through the lens of their cameras, mobile devices can visually observe a user’s environment for detecting faces, understanding spatial scene geometry, and capturing images and videos. This has yielded a wide range of benefits, especially as image sensors have grown to support increasingly higher resolutions and frame rates. With such precision,...

Background Mobile vision systems would benefit from the ability to situationally sacrifice image resolution to save system energy when imaging detail is unnecessary. However, upon any resolution reconfiguration request, current system frameworks stop providing image frames to the application until the reconfiguration completes. Frame delivery is bottlenecked...
