Recently, Video is becoming a catholic medium for e-learning. As per the popularity of online video information over the World Wide Web (WWW) is mostly dependent on user-assigned tags or specification, which is the system by which we can access such videos. However, this system have limitations for retrieval and frequently we want access to the content (pacify) of the video itself is directly matched against a user's query except manually assigned tags or specifications. In e-lecturing videos it contains visual and aural medium: slides of presentation and speech. in this system, we are going to retrieve the text from the videos automatically. To abstract visible information, we apply video content analysis to detect slides and optical character recognition to obtain their text. We abstract textual metadata by applying video Optical Character Recognition (OCR) technology on keyframes and Automatic Speech Recognition (ASR) on lecture audio. The ASR and OCR translate and discover slide text line types are accept for keywords abstraction, in which video and fragment-level keywords are abstracted for video searching on the basis of contents.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
