Quadra-Embedding: Binary Code Embedding with Low Quantization Error [PDF]
Computer Vision and Image Understanding, 2013 Abstract Thanks to compact data representations and fast similarity computation, many binary code embedding techniques have been proposed for large-scale similarity search used in many computer vision applications including image retrieval. Most prior techniques have centered around optimizing a set of projections for accurate embedding.

Diversity Embedded Space–Time Codes
IEEE Transactions on Information Theory, 2008 Rate and diversity impose a fundamental tradeoff in wireless communication. High-rate space-time codes come at a cost of lower reliability (diversity), and high reliability (diversity) implies a lower rate. However, wireless networks need to support applications with very different quality-of-service (QoS) requirements, and it is natural to ask what ...

Embedded Multiple Description Coding of Video
IEEE Transactions on Image Processing, 2006 Real-time delivery of video over best-effort error-prone packet networks requires scalable erasure-resilient compression systems in order to 1) meet the users' requirements in terms of quality, resolution, and frame-rate; 2) dynamically adapt the rate to the available channel capacity; and 3) provide robustness to data losses, as retransmission is ...
