When you think of the words “visual effects”, how long until an image of a green screen comes to mind? The blue/green screen techniques, also known as Chromakey, has been an integral part of the visual effects (VFX) process in the post-production industry for many years, but that’s slowly starting to change. New alternatives are in development that improve post-production efficacy, save labour costs, and foster creative breakthroughs – and they’re being created right here at Carleton University.

In this talk, graduate student Lea (ChangAn) Zhu will discuss how she and another Carleton researcher have developed what they believe is the first five-view camera system prototype. She will explain how the technology perceives real-life scenes from horizontal and vertical directions and fills in blind spots to generate more accurate depth sequences and how the technology can be applied in video object cut-out, visual effects composition, video’s 2D to 3D conversion, and image post-processing. Lea will explain the methodology behind their work, showcase sample shots and discuss how the technology could be used in AR, VR, machine vision and auto-pilot areas.

Speaker Bio

Lea (ChangAn) Zhu is pursuing her PhD of Information Technology at Carleton University, part of the Faculty of Engineering and Design. She received her BEng degree in Digital Media from Beijing Normal University (Zhuhai Campus, China) in 2018 and a MIT degree from Carleton University in 2020. Her research interests include the improvement of realistic 3D computer animation and computer/machine vision applications. She is interested in solving problems in the industry with relevant and practical researches. During her master’s study, her research focused on improving vision-based depth generation results with a new stereo system and applying the system in the film post-production pipeline. The research aims to simplify the element extraction procedures that suffer from high-cost setup or tedious workflow in the film industry. The system brings more options to the post-production pipeline and it enables live-action elements to be composited with spatial depth, producing a more realistic result for the final composition.

About the Series

Ingenious Talks is a special speaker series from the Faculty of Engineering and Design that engages the community in discussions of timely and innovative ideas in engineering, design and technology.
