University of Waterloo and Christie collaborate to improve projection resolution

The collaboration goes back to 2013 and the latest project has focused on the development and production of a patented algorithm that improves laser projection resolution Christie M 4K25 RGB.

Christie and the Image Processing and Vision Laboratory of the University of Waterloo have developed and produced a patented algorithm that drives the improvement of pure laser projector resolution M 4K25 RGB.

The collaboration between the University of Waterloo's Image Processing and Vision Laboratory and Christie began in 2013. And this is the latest success between the institution and Christie., who together recently completed a third two-year research project.

"Years ago, we identified a number of problems for which we were looking for help.", explains Mark Lamm, senior product developer, Christie Advanced Research and Collaboration. "The University of Waterloo group works on camera and vision research and, more recently, in machine learning. It was beneficial for both parties, since we had a problem and they had an interest in solving it".

Waterloo and Christie have collaborated on articles, filings and patents in three projects. Each involved eight to 10 graduate students and included an internship that allowed students to devote two days a week to research.

"Christie's people appreciate the research aspect., as we provide them with ideas and knowledge", comments Paul Fieguth, Professor of Systems Design Engineering at the University of Waterloo. "We are committed to working together and sharing the course of our investigations., as well as contributing ideas to Christie's research goals”.

The research that led to the algorithm for the new M 4K25-RGB pure laser projector began several years ago and resulted in published articles on image enhancement in static images.. The research continued when the team realized that the approach only worked for still images and not for videos..

"We wondered if we could find out in real time the movement of the image and how it detects what a pixel is doing.. Then we had to figure out how to filter and recombine it appropriately.", fieguth says about the research. "That was the crux of most of the work on image resolution that the students were doing.. It took us a while to refine what we were looking for.".

The result of part of the research project is the new patented precision technology 'pixel shift' present in the pure laser projector Christie M 4K25 RGB, that reduces or eliminates typical artifacts found in other pixel shifting technologies and provides up to 4K UHD resolution 120 hz.

The collaboration between the University of Waterloo and Christie is already heading towards a possible fourth research project. "We are very pleased with the research collaboration with the Image Processing and Vision Laboratory at the University of Waterloo", says Lamm. "At Christie we look forward to welcoming the next group of researchers".
