Abstract (in Japanese) (See Japanese page) 
(in English) In computer vision areas, scene text is valuable information for applications including scene understanding, autopilot, blind assistance, etc. Such applications usually work with moving camera and analyze information from video. Benefiting from its self-encoding feature, a neural network is capable of learning pattern from existing datasets and it is widely used at image scene text processing areas. Subject to the amount and quality of video scene text datasets, research in video scene text processing area usually uses image-based neural network or pure image processing algorithm to analyze the information. To overcome this limitation, we have developed a Synthetic Scene Text Video (SSTV) method. It is a data augmentation method which can generate synthetic video from single labeled image based on a synthetic trajectory. Additionally, we propose a magnitude-based mask which alleviates the ambiguity in texts with complex shape and improves the performance compared with conventional binary mask. Using this magnitude-based mask and the SSTV, the F-score of video scene text detection task is improved from 46.34% to 83.47% in comparison with conventional image-based detection network.
