AN ADVANCED METHOD OF OVERLAY TEXT DETECTION, EXTRACTION USING TRANSITION MAP AND INPAINT
|
With the development of video editing technology, there are growing uses of overlay text inserted into video contents to provide viewers with better visual understanding. Most broadcasting videos tend to increase the use of overlay text to convey more direct summary of semantics and deliver better viewing experience. For example, headlines summarize the reports in news videos and subtitles in the documentary drama help viewers understand the content. Sports videos also contain text describing the scores and team or player names. In general, text displayed in the videos can be classified into scene text and overlay text. Scene text occurs naturally in the background as a part of the scene, such as the advertising boards, banners, and so on. In contrast to that, overlay text is superimposed on the video scene and used to help viewers’ understanding. Since the overlay text is highly compact and structured, it can be used for video indexing and retrieval. In this research we focus on extracting the overlay text. As a preliminary preparation, data will be collected as part of this research. The main aim of the research is to propose a novel framework to extract the Overlay text information in video frames.
