  1. Multimedia Systems • Textbook • Any/Most Multimedia Related Books • Reference Papers: • Appropriate reference papers discussed in class from time to time. • You can also bring in papers to be discussed. B. Prabhakaran

  2. Contact Information B. Prabhakaran Department of Computer Science University of Texas at Dallas Mail Station EC 31, PO Box 830688 Richardson, TX 75083 Email: bprabhakaran@utdallas.edu Fax: 972 883 2349 URL: http://www.utdallas.edu/~praba Phone: 972 883 4680 Office: ES 3.706 Office Hours: Fridays 11am – 12noon Other times by appointments through email Announcements: Made in class and on course web page. TA: TBA. B. Prabhakaran

  3. Course Outline Proposed Outline (Discussion Sequence Might be Differetnt): • Introduction to Multimedia Systems • Broad characteristics, requirements, and what makes them different • Operating System Requirements • Disk layout, and scheduling. • Media Characteristics & Compression Techniques • Audio, Images, Video, 3D Models, and 3D Motions • Metadata Generation • Image & Video Segmentation, Shape-based 3D Retrieval B. Prabhakaran

  4. Course Outline Proposed Outline…: • Feature Extraction for Metadata Generation • Image & video features to be extracted for metadata generation • Indexing Structures • R-trees family, Interval trees family, Special structures for 3D Motion data indexing • Streaming Multimedia Data • Video streaming, 3D models streaming, 3D animation streaming • Watermarking Techniques & Security • General strategies, emphasis on 3D watermarking, Security Architectures. • Multimedia Server Architectures • Focusing on Video-on-Demand architectures B. Prabhakaran

  5. Programming Projects • No copying/sharing of code/results will be tolerated. Any instance of cheating in projects will be reported to the University. • Understood: you will need to use open software from the web or other sources. • Must: • Declaration of all codes from open software or the Internet. • Explicit identification of your efforts in the projects. • Deadlines will be strictly followed for projects submissions. • Projects submissions through demo and email. • Demo needed for grading • “Research” oriented projects allowed. B. Prabhakaran

  6. Projects • Typically, programming projects implementing application of your interest. • Mostly individual projects • Projects involving 2 persons (no more than 2) should be sufficiently complex. • Each person’s role should be clearly “visible” • Preferably overlapping topics: e.g., metadata + index structures, index structures + query language, etc. • Types of Projects: • Programming Projects: • Typical expectation • MS and most PhD students • Algorithms/Theory Projects: • Perhaps, PhD students doing research in a particular topic • Combo Projects: • Algorithms + Programming • Perhaps, a team of 1 PhD + 1 MS student B. Prabhakaran

  7. Projects .. • Reasonable expectation from my side • No need for research paper or technical report at semester end. But a demo will be needed. • I encourage you to develop it as a portfolio project • One that can go onto your Resume/CV • Enough support will be provided by me and the TA. • Several resources will be provided • Open software • Research papers • Lab facilities • Discussion time B. Prabhakaran

  8. Projects .. • No restriction on programming language or operating system • TA and I will be available for discussions related to your project • Your responsibility to learn the language and/or the open source you would use. • Don’t use the project to learn a new language/platform. • Don’t ask TA or me to debug your program!! • Project topics: • Suggestions will be given by me next week. • You are encouraged to come up with your own interesting topic. B. Prabhakaran

  9. 2-Track Course • Considering diverse nature of possible projects • Project discussions will be mostly one-on-one • During office hours or by appointment • Class room discussions will be mostly on various techniques and approaches for multimedia systems. B. Prabhakaran

  10. Home works • Approximately 2-3 assignments • Each assignment • Short questions on • Theory discussed in class • Programming resources available for the topic • May need at most couple of hours effort • Can be turned in using • Email • Print outs (allowed, if you hate emails). B. Prabhakaran

  11. Evaluation • Project -- 60% • For “depth” – in one or two focused areas • 15% -- Initial design document (3 – 5 pages) • Within 3+ weeks • 20% -- Mid-term update (6th – 7th week) • Show progress in programming (or design in case of research papers) • Identify troubles or difficulties • Outline completion schedule/steps • 2-3 minutes presentation might be needed. • 25% -- Final demo + documentation • Short presentation in class might be needed • Homework -- 15% • For “breadth” • 2-3 home works. • To “ensure” awareness in topics other than your project topic. • Exam – 25% • For “breadth” • “Simple” but thought-provoking questions B. Prabhakaran

  12. Schedule • Home works will be announced in class and on course web page. • Along with their due dates • Projects schedule (as discussed earlier) • 3rd week – Initial design document (3 – 5 pages) • 6th or 7th week – Mid-term update • End semester – Final demo or presentation • Early finish of projects allowed, if needed by you. • Exam • Last day of class or per UTD schedule.
