Christie and University of Waterloo collaborate
- Details
The collaboration between the Vision and Image Processing Lab at the University of Waterloo and Christie began in 2013.
“Years ago, we wrote out a set of problems we’d like help with,” says Mark Lamm, senior product developer, advanced research and collaboration, Christie. “The group at the University of Waterloo works on vision and camera research, and more recently, machine learning. It was a match – we had problems and they had interest.”
Waterloo and Christie have collaborated on papers, presentations, and patents over the three projects. Each project involved eight to 10 graduate students and included an internship which allows students to dedicate two days a week to Christie research.
“Christie has interesting problems. The people at Christie appreciate the research aspect – we’re providing ideas and insight,” says Paul Fieguth, professor in systems design engineering at the University of Waterloo. “We’re committed to working jointly and talking about where our research is going and next directions, 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 papers on image enhancement for static images. The research continued as the team realised that the approach only worked for static images, and not video.
The team “went back to the drawing board,” says Lamm. “Alex Wong, a systems design professor at the University of Waterloo, helped us come up with a new approach.”
The result of part of the research project is the new precision pixel shift technology in the Christie M 4K25 RGB pure laser projector, which reduces or eliminates typical artifacts found in other pixel-shifting technologies, provides UHD 4K resolution at up to 120Hz.
The collaboration between the University of Waterloo and Christie is already headed toward a possible fourth research project.
“We’re very pleased with the research collaboration with the University of Waterloo’s Vision and Image Processing Lab,” says Lamm. “We look forward to welcoming the next group of researchers to Christie.”
