The motivation is to devise new multimedia technologies that are suitable for better representation of instructional videos by exploiting the temporal redundancies present in the original video. This solves many of the issues related to the memory and bandwidth limitation of lecture videos. The various methods described in the book focus on a key-frame based approach which is used to time shrink, repackage and retarget instructional videos. All the methods need a preprocessing step of shot detection and recognition, which is separately given as a chapter. We find those frames which are well-written and distinct as key-frames. A super-resolution based image enhancement scheme is suggested for refining the key-frames for better legibility. These key-frames, along with the audio and a meta-data for the mutual linkage among various media components form a repackaged lecture video, which on a programmed playback, render an estimate of the original video but at a substantially compressed form. The book also presents a legibility retentive retargeting of this instructional media on mobile dev | | 出版日期 | Book 2012 | | 关键词 | Horizontal projection profile; Ink pixel; Key-frame extraction; Key-hole image; Local content delivery; P | | 版次 | 1 | | doi | https://doi.org/10.1007/978-1-4614-3837-3 | | isbn_softcover | 978-1-4899-8577-4 | | isbn_ebook | 978-1-4614-3837-3 | | copyright | Springer Science+Business Media New York 2012 |
