Edge state quantization: vector fields in Rindler

Journal of High Energy Physics, 2018
We present a detailed discussion of the entanglement structure of vector fields through canonical quantization. We quantize Maxwell theory in Rindler space in Lorenz gauge, discuss the Hilbert space structure and analyze the Unruh effect.

Adaptive Vector Quantization for Lossy Compression of Image Sequences

Algorithms, 2017
In this work, we present a scheme for the lossy compression of image sequences, based on the Adaptive Vector Quantization (AVQ) algorithm. The AVQ algorithm is a lossy compression algorithm for grayscale images, which processes the input data in a single-

A mean-removed variation of weighted universal vector quantization for image coding [PDF]

, 1993
Weighted universal vector quantization uses traditional codeword design techniques to design locally optimal multi-codebook systems. Application of this technique to a sequence of medical images produces a 10.3 dB improvement over standard full search ...
