摘要

本文介绍了基于文本的视频索引和检索实验。由于预期的OCR误差和视频文本缺乏语义广度，我们提出了两种解决方案:1)扩展查询词的语义，2)使用Glimpse进行近似匹配而不是精确匹配。结果表明，语义扩展和瞥见在基于文本的视频检索中发挥着重要作用。

Video indexing and retrieval based on recognized text

In this paper we present our experiments on text-based video indexing and retrieval. Due to expected OCR errors and the lack of semantic breadth in video text, we proposed two solutions: 1) expanding the semantics of the query word, and 2) using Glimpse to perform approximate matching instead of exact matching. The results we achieved showed that semantic expansion and Glimpse can play important roles in video retrieval based on text.
