We propose a fully automatic method for summarizing and indexing unstructured presentation videos based on text extracted from the projected slides. We use changes of text in the slides as a means to segment the video into semantic shots. Unlike precedent approaches, our method does not depend on availability of the electronic source of the slides, but rather extracts and recognizes the text directly...
events in soccer video using on-screen texts. The proposed approach is completely automatic and independent to languages since it recommends the users to query events by keywords in image-form which are agents of clusters of stationary on-screen textboxes which are localized and extracted properly by a novel mechanism
Semantic soccer video analysis has attracted more and more attention recently. In this paper, we present a football event detection method by using multiple feature extraction and fusion. Instead of using low-level features, the proposed method is built upon visual, auditory features, text and audio keywords
Overlaid text appears frequently in broadcast sports video. They provide supplementary information regarding the happenings of a particular game. Examples include important events of interest such as bookings and substitutions in a soccer match. Furthermore, overlaid-text is displayed when a particular concept of interest is happening or has happened. This paper presents a technique to automatically...
content providers rely on keywords to perform the classification, while active techniques for automatic video classification focus on utilizing multi-modal features. However, in our settings, we argue that both approaches are not sufficient to solve the problem effectively. Keywords based method is very limited in terms of
beforehand. Approach here is to provide processed images to the Tesseract OCR to get better results than directly providing the raw video frames to the Tesseract OCR. The ticker text recognized can further be used for indexing of news videos on the basis of recognized keywords. Indexing of news videos is important for news
