Subject: Using high res photos to enhance inferior video of the same scene

For IP, if you wish.

I thought this was particularly clever, and produces some impressive
results:

"We present a framework for automatically enhancing videos of a static
scene using a few photographs of the same scene. For example, our
system can transfer photographic qualities such as high resolution,
high dynamic range and better lighting from the photographs to the
video. Additionally, the user can quickly modify the video by editing
only a few still images of the scene. Finally, our system allows a
user to remove unwanted objects and camera shake from the video. These
capabilities are enabled by two technical contributions presented in
this paper. First, we make several improvements to a state-of-the-art
multiview stereo algorithm in order to compute view-dependent depths
using video, photographs, and structure-from-motion data. Second, we
present a novel image-based rendering algorithm that can re-render the
input video using the appearance of the photographs while preserving
certain temporal dynamics such as specularities and dynamic scene
lighting."
