On Interpolation and Resampling of Discrete Data (2008)
Pouya Dehghani Tafti, Student Member, Shahram Shirani, Senior Member, Xiaolin Wu, Senior Member
Abstract—This letter introduces a new representation of discrete signals based on the mathematical notions of functionals and continuous dual spaces. A new and more general sampling theorem is also...
On RD Optimized Progressive Image Coding Using JPEG (2007)
Jaehan In, Shahram Shirani, Faouzi Kossentini
Among the many di#erent modes of operations allowed in the current JPEG standard, the sequential and progressive modes are the most widely used. While the sequential JPEG mode yields essentially the...
Jpeg Compliant Efficient Progressive Image Coding (2007)
Jaehan In, Shahram Shirani, Faouzi Kossentini
Among the different modes of operations allowed in the current JPEG standard, the sequential and progressive modes are the most widely used. While the sequential JPEG mode yields essentially the same...
Reconstruction of JPEG Coded Images in Lossy Packet Networks (2007)
Shahram Shirani, Faouzi Kossentini, Samir Kallel, Rabab Ward
In this paper packetization and reconstruction algorithms in transmission of JPEG coded images over lossy channels are proposed. An interleaving method is devised that maximizes the minimum distance...
University of British Columbia, (2007)
Shahram Shirani, Faouzi Kossentini, Rabab Ward
In this paper, reconstruction of missing data in transmission of baseline JPEG coded images in error prone environments is investigated. A method for estimating the missing DC coecients of blocks in...
To reliably transmit video over error-prone channels, the data should be both source and channel coded. When multiple channels are available for transmission, the problem extends to that of...
Guy Côté, Shahram Shirani, Faouzi Kossentini
In this paper, we describe an e#ective method for increasing error resilience of video transmission over bit error prone networks. Rate-distortion optimized mode selection and synchronization marker...
