Display tracking using blended images with unknown mixing ratio as a template
Akifumi Goto, Shingo Kagami, Koichi Hashimoto · 2016
This paper describes a display tracking method employing blended multiple images with unknown mixing ratio as a template, which estimates the geometrical transformation and mixing ratio simultaneously. We propose a fast computational algorithm for the above problem that enables high-frame-rate visual tracking. We demonstrate an application to fast tracking projection of a grayscale image by a high-speed DLP (Digital Light Processing) projector, in which the image is composed of multiple bit planes, and an application to tracking of a movie displayed in a liquid crystal display panel, in which the movie is composed of multiple grayscale images.
