Summary of the technology
Many imaging devices produce signals of unsatisfactory resolution (e.g. a photo from a cell-phone camera may have low spatial resolution or a video from a web camera may have both spatial and temporal low resolution).
Previous methods for Super-Resolution (SR) require multiple images of the same scene, or else an external database of examples. This method applies digital processing to reconstruct more satisfactory high-resolution signals. ). The algorithm exploits the inherent local data redundancy within visual signals (redundancy both within the same scale and across different scales). This method provides the ability to perform SR from a single image (or a single visual source. Additional examples of the methods' capabilities can be found here:

Background and Unmet Need
Ever taken a digital photograph and then found out you had missed the fine details that made the scene so impressive visually? Many imaging devices produce signals of unsatisfactory resolution (e.g. a photo from a cellphone camera may have low spatial resolution or a video from a web camera may have both spatial and temporal low resolution). Applying a Photoshop sharpen filter may make the photo appear sharper, but such filters are lossy – they actually reduce the amount of fine detail in the image.
The Solution
Prof. Michal Irnai and her team developed a method for enhancing the spatial and or temporal resolution (if applicable) of an input signal such as images and videos from a single source.
Technology Essence
This method applies digital processing to reconstruct more satisfactory high resolution signals. Previous methods for Super-Resolution (SR) require multiple images of the same scene, or else an external database of examples.
This method provides the ability to perform SR from a single image (or a single visual source). The algorithm exploits the inherent local data redundancy within visual signals (redundancy both within the same scale, and across different scales). This super-resolution process pulls unseen details from the nooks and crannies of a single digital photograph. Their process can capture true detail which cannot be seen in the original image.

Applications and Advantages
Applications
- Enhancing the spatial resolution of images
- Enhancing the spatial and or temporal resolution of video sequences
- Enhancing the spatial and or temporal resolution (if applicable) of other signals (e.g., MRI, fMRI, ultrasound,
- possibly also audio, etc.
Advantages
No need for multiple low-resolution sources or the use of an external database of examples.
Superior results are produced due to exploitation of inherent information in the source signal.

About Yeda
Yeda ("Knowledge" in Hebrew) Research and Development Company Ltd. is the commercial arm of the Weizmann Institute of Science (WIS) and is the second company of its kind established in the world.
WIS is one of the world’s leading multidisciplinary basic research institutions in the natural and exact sciences. It is located in Rehovot, Israel, just south of Tel Aviv. It was initially established as the Daniel Sieff Institute in 1934, by Israel and Rebecca Sieff of London in memory of their son Daniel. In 1949, it was renamed for Dr. Chaim Weizmann, the first President of the State of Israel and Founder of the Institute.
Yeda initiates and promotes the transfer to the global marketplace of research findings and innovative technologies developed by WIS scientists. Yeda holds an exclusive agreement with WIS to market and commercialize its intellectual property and generate income to support further research and education.
Since 1959 Yeda has generated the highest income per researcher compared to any other TTO worldwide. Weizmann has generated a number of groundbreaking therapies, such as Copaxone, Rebif, Tookad, Erbitux, Vectibix, Protrazza, Humira, and recently the CAR-T cancer therapy Yescarta.
Yeda performs the following activities:
◣ Identifies and assesses research projects with commercial potential.
◣ Protects the intellectual property of WIS and its scientists.
