Generalizations of permutation source codes
… codebook. In the second approach, we introduce frame permutation quantization (FPQ), a new vector quantization technique using finite frames. In FPQ, a vector is encoded using a permutation source code to quantize its frame expansion. This means that the encoding is a partial ordering of the …

Frames In Hilbert C*-modules
Since the discovery in the early 1950's, frames have emerged as an important tool in signal processing, image processing, data compression and sampling theory etc. Today, powerful tools from operator theory and Banach space theory are being introduced to the study of frames producing deep results …

Distortion-optimal parallel MRI with sparse sampling: from adaptive spatio-temporal acquisition to self-calibrating reconstruction
… Moreover, the unified multi-channel sampling framework explicitly accounts for speed limitations of gradient encoding, provides performance guarantees on achievable image quality both in terms of noise gain and aliasing distortion, and allows for analysis of the method's robustness to model …
