Journal ArticleDOI
Multiple description coding: compression meets the network
TL;DR: By allowing image reconstruction to continue even after a packet is lost, this type of representation can prevent a Web browser from becoming dormant, and the source can be approximated from any subset of the chunks.
Journal ArticleDOI
Quantized Frame Expansions with Erasures
TL;DR: This paper places frames in a new setting, where some of the elements are deleted, and shows that a normalized frame minimizes mean-squared error if and only if it is tight.
Journal ArticleDOI
Quantized overcomplete expansions in IR/sup N/: analysis, synthesis, and algorithms
TL;DR: Results suggest that optimal reconstruction methods will yield O(1/r/sup 2/) mean-squared error (MSE), and that consistency is sufficient to insure this asymptotic behavior.
Journal ArticleDOI
Theoretical foundations of transform coding
TL;DR: Discusses various aspects of transform coding, including: source coding, constrainedsource coding, the standard theoretical model fortransform coding, entropy codes, Huffman codes, quantizers, uniform quantization, bit allocation, optimal transforms, transforms visualization, partition cell shapes, autoregressive sources and departures form the standard model.

TL;DR: First-photon imaging is introduced, which is a computational imager that exploits spatial correlations found in real-world scenes and the physics of low-flux measurements, and recovers 3D structure and reflectivity from the first detected photon at each pixel.
