Multimedia Research Lab

The goal of Multimedia Research Lab (MRL) is to conduct research on all aspects of multimedia systems including multimedia data processing, computing and the related communication issues. In today’s age of Information Technology, Multimedia data refers to Audio, Images, Video, Graphics and Text data. Currently the MRL lab has been focusing on research on video, image and audio processing algorithms, coding and their real-time implementation on embedded platforms.

 

The lab with state-of-the-art facilities is now about two and a half years old and was established through external funding. During this time with the growing number of students and researchers associated with the lab 17 research publications have been realized. In the last two years MRL has also successfully managed to deliver an industrial project related to the development of a proprietary Video Conferencing system. It is the objective of the lab to steer its effort towards new emerging research areas including multi-view image and video processing, Mobile TV and 3D-TV.

MRL team believes in encouraging collective research among its faculty members, graduates students and external research groups. At the same time we want to strengthen our interaction with industry through collaborative R&D projects. Currently research is being done on Motion Compensated Wavelet based video coding, efficient implementation issues of Fine Grain Video Scalability, efficient prediction algorithms for real-time implementation of H.264 and MPEG4 standards, Constrained but fast object extraction and tracking for real-time multimedia applications, proprietary error resilient audio/video codec for multipoint video conferencing on embedded platform over diverse networks and CELP and HVXC based speech/audio codecs. In the future MRL plans to work on Multi-view video processing, 3D-TV and Free View TV standardization and Mobile TV standard for 4G wireless Networks.

Projects

Advanced Techniques for monoscopic and multiview video coding

Investigator: Dr. Nadeem A. Khan
Project Duration: March 2007 - March 2008
Funded by LUMS ( Rs. 180000 )


Wavelet Coding

Investigator: Dr. Nadeem A. Khan
Project Duration: December 2006 - December 2007
Funded by LUMS ( Rs. 60000 )


Video Segmentation: Extraction and tracking of objects of interest in videos

Investigator: Dr. Nadeem A. Khan
Project Duration: January 2005 - January 2006
Funded by LUMS ( Rs. 95500 )
The proposal title mention general 'objects of interest' in videos but the current focus has been on detection of faces rather than on arbitrary objects. The approach currently taken involves skin detection and the use of edges to extract the entire face region in talking-head videos. The min thrust has been to focus on an approach that is very fast, so that it can be used in real time video applications.

Efficient Motion Estimation Algorithms in H.264/AVC Standard

Investigator: Dr. Shahid Masud/Nadeem A. Khan
Project Duration: February 2004 - February 2005
Funded by LUMS ( Rs. 206400 )
H.264 is a video compression standard being jointly developed by ITU-T Video Coding Experts Group and ISO/IEC Motion Picture Expert Group. The main goal of this standardization effort is enhanced compression performance and provision of a network-friendly packet-based video representation. The applications primarily include video communications over the Internet and mobile wireless channels. Various robust and error-resilience feature have therefore been incorporated in these recommunications.
