英文摘要

Video subtitles could be defined as the combination of visualized subtitles in frames and textual content recognized from speech, which play a significant role in video understanding for both humans and machines. In this paper, we propose a novel Watch and Listen for Multimodal Subtitle Recognition (WL-MSR) framework to obtain comprehensive video subtitles, by fusing the information provided by Optical Character Recognition (OCR) and Automatic Speech Recognition (ASR) models. Specifically, we build a Transformer model with mask and crop strategies and multi-level identity embeddings to aggregate both the textual results and features of the two modalities. To pre-filter out the noise items in OCR results before fusion, we adopt an OCR filter based on ASR results and confidence scores of OCR. By combining these techniques, our solution wins the 2nd place in Multimodal Subtitle Recognition Challenge on ICPR2022.
