Occlusion classifiers for picture rate conversion

SPIE Proceedings, 2009
Occlusion detection is an essential ingredient in high quality picture rate up-conversion and view interpolation applications. Many integrated approaches to occlusion detection and classification have been proposed, particularly in the stereo literature.

A new converse in rate-distortion theory [PDF]

2012 46th Annual Conference on Information Sciences and Systems (CISS), 2012
This paper shows new finite-blocklength converse bounds applicable to lossy source coding as well as joint source-channel coding, which are tight enough not only to prove the strong converse, but to find the rate-dispersion functions in both setups.

Catalytic Conversion of Polysulfides on Single Atom Zinc Implanted MXene toward High‐Rate Lithium–Sulfur Batteries

Advanced Functional Materials, 2020
Although lithium–sulfur (Li–S) batteries are one of the most promising energy storage devices owing to their high energy densities, the sluggish reaction kinetics and severe shuttle effect of the sulfur cathodes hinder their practical applications. Here,

High frame rate video conversion

IP Streams, Control, and Production, 2014
SMPTE is discussing high frame rates within the Ultra-High-Definition Television (UHDTV) Study Group and, in particular, conversions from high frame rates to today's integer and fractional standards. Although it seems an easy problem to upconvert and downconvert between frame rates when there is a simple multiplier, for example, between 119.88 and 59 ...

RECONFIGURABLE NEWTON STRUCTURE FOR SAMPLE RATE CONVERSION

2018 IEEE Global Conference on Signal and Information Processing (GlobalSIP), 2018
In this paper, a novel method for designing reconfigurable Newton structure is proposed. The Newton structure is a variable fractional delay filter that implements Lagrange interpolation only. This structure has been extended later in the literature to implement other types of interpolation, such as Spline and Hermite interpolations.

Enhancement of CO2 Conversion Rate and Conversion Efficiency by Homogeneous Discharges

Plasma Chemistry and Plasma Processing, 2012
The CO2 conversion rate and conversion efficiency were greatly enhanced by homogeneous dielectric barrier discharges generated in our experiment. Influence of CaO–B2O3–SiO2 glass addition on dielectric properties and microstructures of Ca0.8Sr0.2TiO3 were investigated for the purpose of discerning the effect of dielectric barrier material on the ...

Femtosecond-rate space-to-time conversion

Journal of the Optical Society of America B, 2000
A real-time spatial–temporal processor based on cascaded nonlinearities converts space-domain images to time-domain waveforms by the interaction of spectrally decomposed ultrashort pulses and spatially Fourier-transformed images carried by quasi-monochromatic light waves.

Dose-rate conversion factors: update

Ancient TL, 2011
In the field of luminescence and electron spin resonance dating, dose rate conversion factors are widely used to convert concentrations of radioactive isotopes to dose rate values. These factors are derived from data provided by the National Nuclear Data

Conversion and equilibration rates of hydrogen on nickel

Discussions of the Faraday Society, 1966
The pH2 conversion rate has been compared with that for oD2 and H2+ D2→ 2HD on nickel wires rigorously cleaned in vacuo of 10–10 torr. The rates are significantly higher than on evaporated films, prepared under similar conditions but still possibly contaminated. The results at 1 torr fall into three temperature ranges (a) 330–400°K, a fractional order (

A flexible sampling-rate conversion method

ICASSP '84. IEEE International Conference on Acoustics, Speech, and Signal Processing, 2005
A digital resampling method is proposed which allows non-uniform and time-varying resampling. The method is based on interpolated look-up in a large table of filter coefficients. One filter table handles all conversion factors. Formulas are given for determining the size of look-up table needed for a given precision requirement.
