Remote Sensing Low Signal-to-Noise-Ratio Target Detection Enhancement [PDF]

Sensors, 2023
In real-time remote sensing application, frames of data are continuously flowing into the processing system. The capability of detecting objects of interest and tracking them as they move is crucial to many critical surveillance and monitoring missions ...

On the definition of signal-to-noise ratio and contrast-to-noise ratio for FMRI data. [PDF]

PLoS ONE, 2013
Signal-to-noise ratio, the ratio between signal and noise, is a quantity that has been well established for MRI data but is still subject of ongoing debate and confusion when it comes to fMRI data.

Realizing nearly-zero dark current and ultrahigh signal-to-noise ratio perovskite X-ray detector and image array by dark-current-shunting strategy

Nature Communications, 2023
Although perovskite X-ray detectors have revealed promising properties, their dark currents are usually hundreds of times larger than the practical requirements.
