Scalable Compression and Rendering of Textured Terrain Data
Several sophisticated methods are available for efficient rendering of out-of-core terrain data sets. For huge data sets the use of preprocessed tiles has proven to be more effici...

Generalized bitplane-by-bitplane shift method for JPEG2000 ROI coding
One interesting feature of the new JPEG2000 image coding standard is support of region of interest (ROI) coding using the maximum shift (Maxshift) method, which allows for arbitra...

Generalized Multiple Description Coding Through Unequal Loss Protection
We use unequal amounts of explicit channel coding for generalized multiple description coding. Our solution can use any progressive source coder and it disperses information equal...

Robust perceptual image hashing using feature points
Perceptual image hashing maps an image to a fixed length binary string based on the image's appearance to the human eye, and has applications in image indexing, authenticatio...

RD-Optimization of Hierarchical Structured Adaptive Vector Quantization for Video Coding
This paper contains two contributions to very-low-bitrate video coding. First, we show that in contrast to common practice incremental techniques for rate-distortion optimization ...
