Gaussian Blurring-Deblurring for Improved Image Compression
The deblurring of Gaussian blur by inverting the action of the diffusion equation has long been known. This technique is interesting but without much practical application since th...

Unequal Loss Protection for H.263 Compressed Video
We study the application of Unequal Loss Protection (ULP) algorithms to motion-compensated video over lossy packet networks. In particular, we focus on streaming video applications...

Spatiotemporal-chromatic structure of natural scenes
We investigate the implications of a unified spatiotemporal-chromatic basis for compression and reconstruction of image sequences. Different adaptive methods (PCA and ICA) are app...

Perceptual media compression for multiple viewers with feedback delay
Human eyes have limited perception capabilities; for example, only 2 degrees of our 140 degree vision field provide the highest quality of perception. Due to this fact the idea of...

Subjective Quality Analysis of Bit Rate Exchange Between Temporal and SNR Scalability in the MPEG4 SVC Extension
It is well known that a compression trade-off exists between the spatial and temporal video quality. Various temporal scalability techniques have been considered for lowering the ...
