Reading Between the Lanes: Text VideoQA on the Road
This addresses the challenge of text-aware multimodal reasoning for in-vehicle support systems, but it is incremental as it primarily provides a new dataset.
The authors tackled the problem of scene text recognition in driving videos for driver assistance by introducing RoadTextVQA, a new dataset with 3,222 videos and 10,500 questions, and found that state-of-the-art models show significant room for improvement.
Text and signs around roads provide crucial information for drivers, vital for safe navigation and situational awareness. Scene text recognition in motion is a challenging problem, while textual cues typically appear for a short time span, and early detection at a distance is necessary. Systems that exploit such information to assist the driver should not only extract and incorporate visual and textual cues from the video stream but also reason over time. To address this issue, we introduce RoadTextVQA, a new dataset for the task of video question answering (VideoQA) in the context of driver assistance. RoadTextVQA consists of $3,222$ driving videos collected from multiple countries, annotated with $10,500$ questions, all based on text or road signs present in the driving videos. We assess the performance of state-of-the-art video question answering models on our RoadTextVQA dataset, highlighting the significant potential for improvement in this domain and the usefulness of the dataset in advancing research on in-vehicle support systems and text-aware multimodal question answering.
