This work introduces mathematical properties for functionals that evaluate the complexity of vector quantization. Considering complexity functionals with such properties, it is shown that fundamental limits hold for the quantization trade-off between distortion, rate, and complexity. Part of the discussion presented in 2008 by Gray et al., [6], is extended, by replacing the original log codebook size...
Several methods for evaluation of the complexity of data compression systems and for including complexity measures in the traditional rate-distortion analysis have been published in recent works. In this work, we indicate that the relationship between rate-distortion performance and complexity for some practical coding schemes—entropy-constrained vector quantization (ECVQ) and interpolative vector...
Infrared focal plane arrays have many military, industrial, medical, and scientific applications that require high-resolution and high-performance read-out electronics. In applications involving InGaAs sensor arrays, data read-out can be carried out by circuits implemented with 0.35μm CMOS technology. In this paper we propose a dynamically regulated cascode current mirror for pixel read-out. From...
