Overview : Digital Video Processing 1/28/20162 Video Acquisition Computer Graphics Video Compression Video Transmission Video Analysis Video Manipulation Video Display Computer Vision Video Database Digital Video Processing
Cont… Computer graphics: CG are graphics created using computers and the representation of image data by a computer specifically with help from specialized graphic hardware and software. Video Acquisition: It is the process of converting an analog video signal—such as that produced by a video camera or DVD player to digital video. Video Editing: It is the process of manipulating and rearranging video shots to create a new work.
Cont… Video Compression: Video takes up a lot of memory. Uncompressed footage from a camcorder takes up about 17MB per second of video. Because it takes up so much space, video must be compressed before it is put on the internet. It compressed just means that the information is packed into a smaller space.
Video analysis: The terms video analytics and video analysis are broad descriptors of a number of new technologies and evolutions in the field of video surveillance and security. These changes are making security systems more effective and efficient. One of the most basic features of video analysis systems is motion detection: technology that identifies and alerts when movement occurs. Video display: A display device is an output device for presentation of information in visual or tactile form.
Cont… Video database: The Video Database settings allow you almost complete control over your Video Database. You can control what data is downloaded for your movies from IMDB and what images display, including whether you wish to download and use fanart or not. Computer Vision: It is a field that includes methods for acquiring, processing, analyzing and understanding images and in general, high- dimensional data from the real world in order to produce numerical or symbolic information e.g., in the forms of decisions.
Video Acquisition Video acquisition is done through following 1/28/20167 Video camera VHS digitization computer-generated Digital Video Processing
8 Acquisition-Related Problems Video camera What if camera is not kept still? Why is it difficult to improve the spatial resolution of video cameras? VHS digitization What if VHS contains some scratches? How to handle interlaced video? Computer-generated How is this type of video different? Shouldn’t we have a separate coding algorithm for this type of video? 1/28/2016 Digital Video Processing
Video Manipulation Why Video manipulation? Fight against a non-ideal video acquisition (e.g., analog heritage, film scratches, limited resolution) or transmission environment Create new and artificial video content (e.g., spatial-temporal interpolation, background/foreground modification) 1/28/20169 Digital Video Processing
In the age of spectacular technology, shifts one of the most significant has been emergence of digital video as an important aspect in daily life. While the Internet has certainly vividly changed the way in which we obtain information. Due to powerful medium of video. Ongoing advancemen in handheld mobile devices has now been dominated by easier wireless Internet access that is enhanced by rich video and multimedia content.

Benefit of Digital Video On topic videos can help students engage with subject matter on a deeper level. Showing videos can help keep class feeling lively and new while sparkling discussion. Interest coming with innovative way to teach lesson better. 1/28/2016Digital Video Processing24
Medical Imagining Scientific applications such as medical imaging. 1/28/2016Digital Video Processing25
Cont… For de-noising, restoration and super resolution. It have been rapidly gaining popularity due to the proliferation of entry-level, low resolution camcorders, web cams, cell phone cameras, and low-cost surveillance systems. A longstanding need exists for advanced processing methods in following research field. 1/28/2016Digital Video Processing26

Digital Video Processing: Research Field There are following advantage of digital video processing In-class discussion it is strongly encouraged especially for hot topics and current trends that will be helpful for latest knowledge. After each chapter, we will spend some time on brainstorming – identify good topics for your research. Although the lecturing style of this course is deductive, computer assignments and course projects involve inductive teaching which will be helpful for your research. 1/28/2016Digital Video Processing32
Video Authentication It is a process that is used to ascertain the trustworthiness of a digital video. In other words, a video authentication system ensures the integrity of digital video, and verifies that the video taken into use has not been tampered 1/28/2016Digital Video Processing34 Original ImageTampered Image www.acs.uwinnipeg.ca
