Some other super-resolution examples
Javier Mateos

Outline
• Other applications of super-resolution
– Demosaicing – Superresolution from multisensors

• Multi-Dimensional Signal Processing(MDSP) • Commercial software
– – – – QE Superresolution PhotoAcute Cognitech Video Investigator Other commercial software

Other approaches to superresolution
• Demosaicing Improves color imagesfrom a single CCD camera • Superresolution from multisensors Combine images from a set of shifted sensors

Multi-Dimensional Signal Processing (MDSP)
• Implements several super-resolution methods by Prof. Elad and Prof. Milanfar. • For academic (Prof. Milanfar) andcommercial use (MotionDSP, Inc.) • Allows super-resolution for gray scale and color (demosaicing) images.
