Colorization Of High-Frame-Rate Monochrome Videos Using Synchronized Low-Frame-Rate Color Data

The frame rate of a color camera is usually limited by its maximum data bandwidth. To obtain high-frame-rate color videos, we propose to colorize high-frame-rate monochrome videos using data from a system composed of one high-frame-rate monochrome camera and two low-frame-rate color cameras. The cameras are synchronized by external triggering signals. With stereo matching andmotion estimation algorithms, colorization of high-frame-rate monochrome videos can be realized. The system is very cost-effective, and the processing steps can be fully automated as demonstrated in the paper.
