Abstract We present solutions for
enhancing the spatial and/or temporal resolution of videos. Our algorithm
targets the emerging consumer-level hybrid cameras that can simultaneously
capture video and high-resolution stills. Our technique produces a high spacetime resolution video using the high-resolution
stills for rendering and the low-resolution video to guide the reconstruction
and the rendering process. Our framework integrates and extends two existing
algorithms, namely a high-quality optical flow algorithm and a high-quality
image-based-rendering algorithm. The framework enables a variety of
applications that were previously unavailable to the amateur user, such as
the ability to (1) automatically create videos with high spatiotemporal
resolution, and (2) shift a high-resolution still to nearby points in time to
better capture a missed event. Demo
