High Resolution Stereo in Real Time

2008
Efficient stereo matching algorithms search for corresponding points along the epipolar lines defined by the camera properties and configuration. In real cameras, lens distortions and misaligned cameras lead to sloping curved epipolar lines on the raw images.

Time-frequency structure of the high-resolution ECG

Journal of Electrocardiology, 1994
This study considers the problem of representing high-resolution ECG (HRECG) signals in the time-frequency plane using spectrotemporal mapping (STM). High-resolution ECG signal components overlap in both time and frequency. The central issue with STM techniques is whether sufficient time-frequency resolution exists to discriminate normal and abnormal ...

A note on high resolution timing

ACM SIGMETRICS Performance Evaluation Review, 1974
The ability to accurately time the execution of sequences of machine instructions is an important tool in the tuning and evaluation of computer hardware and software. The complexity of modern hardware and software systems often makes accurate timing information difficult to obtain [1].

High-resolution processing for time-lapse seismic

First Break, 2004
Time-lapse seismic technology is moving from measurement of qualitative variations to quantitative analysis of fluid saturation and pressure variations. Increasing the resolution of time-lapse seismic data relative to the reservoir body scale offers the possibility of even more accurate measurements.

High-resolution real-time ultrasonic scanner

Ultrasound in Medicine & Biology, 1992
High spatial resolution is required for echographic exploration of the skin, microvessels or small laboratory animals. With the scanner described here, high resolution is obtained by means of a strongly focused, wide-band 17 MHz center frequency transducer (-6 dB bandwidth: 22 MHz).

A High Time Resolution Polarimeter for Laser Analysis

Applied Optics, 1966
A technique that has a time resolution capability of better than 0.1 microsec has been developed for the measurement of the polarization of a light beam. This technique has proven useful in measuring the polarization of pulsed laser beams because changes in polarization from spike to spike also may be measured.

SCALING OF RETURN TIMES FOR A HIGH-RESOLUTION RAINFALL TIME SERIES

Fractals, 2002
Rainfall is a highly intermittent field over a wide range of time and space scales. We study a high resolution rainfall time series exhibiting large intensity fluctuations and localized events. We consider the return times of a given intensity, and show that the time series composed of these return times is itself also very intermittent, obeying to a ...

High-resolution and high-sensitivity optical-time-domain reflectometer

Optics Letters, 1988
We demonstrate a photon-counting optical-time-domain reflectometer (OTDR) operating at a wavelength of 0.85 microm at room temperature with high sensitivity (3 x 10(-15) W) at high resolution (1.5 cm, 150 psec). Measurements of splice losses and Rayleigh scattering losses less then 0.1 dB with centimeter resolution are demonstrated to be possible with ...

High Resolution Time Lapse Time Strains

Proceedings, 2018
Summary High resolution, low noise time strain estimates are derived through a deliberate choice of penalty function in the time shift inversion. In seismic time lapse analysis, time shifts and their derivative time strain has the potential to directly pin-point transit time changes inside the producing reservoir.
