Summary of the technology

Data storage of images and videos became a real issue in the last years when pictures and videos are taken and shared more often, and the memory devices aren’t being minimized fast enough.
Prof. Michal Irani and her team have developed an algorithm that can resize images while keeping the important features without any undesired artifacts.


The Need

Camera phones and social media made images and videos more accessible and widespread than ever before.
When taking a picture, we capture additional less important features that consume memory along with the focused object. When resizing images, it is hard to remove the less important features while keeping the high resolution of the main objects.

The Solution

Bidirectional Similarity offers a new approach to summarizing visual data (images and video) based on optimization of well-defined similarity measures.

Technology Essence

The algorithm uses an iterative process, gradually reducing the image size while keeping all source patches in the target image without introducing visual artifacts in the input data. Utilizing a similarity index, the algorithm identifies redundant information and compromises the “less important” data while generating the required target image or video.

Applications and Advantages


Resizing app

  • Creation of Thumbnails
  • Adjustment of images to different screen sizes (TV-cellular etc.)
  • Optimization of space-time patches in video processing

Image montages

Automatic image & video cropping


  • Provides better resolution and, in many cases, reduces distortion compared to scaling
  • Reduces (or avoids) loss of important data compared to cropping
  • Allows importance-based summarization even when vital information is widespread and hard to define
  • Uses quantitative objective similarity measure
  • Offers a generic tool for different image processing applications (synthesis, montage, reshuffling etc.)

Development Status


Market Opportunity

Reducing the consumed memory of each picture by resizing is highly relevant for mobiles, where memory storage is limited. This algorithm could also be used as a “smart cropping” tool for image processing software (such as Photoshop, etc.) or “smart fitting” of pictures to different screen sizes for smart TVs.

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.
