Illuminating the darkness: A pyramid‐based approach with lightness attention and noise suppression
Electronics Letters, 2023 Abstract Images taken in low‐light conditions often suffer from reduced contrast, amplified noise, and colour distortions. Such degradation falls short of viewer expectations and negatively impacts high‐level tasks, such as object detection.

GIS Mapping of Short-Term Noisy Event of Diwali Night in Lucknow City
ISPRS International Journal of Geo-Information, 2021 Noise is a universal problem that is particularly prominent in developing nations like India. Short-term noise-sensitive events like New Year’s Eve, derby matches, DJ night, Diwali night (celebration with firecracker) in India, etc.

Enhanced-alignment Measure for Binary Foreground Map Evaluation [PDF]
International Joint Conference on Artificial Intelligence, 2018 The existing binary foreground map (FM) measures address various types of errors in either pixel-wise or structural ways. These measures consider pixel-level match or image-level information independently, while cognitive vision studies have shown that ...

Mobile crowdsensing accuracy for noise mapping in smart cities
Automatika, 2018 This paper deals with the problem of traffic noise in urban areas in terms of noise mapping. It explains in detail the Mobile Crowdsensing (MCS) method and, furthermore, compares the results obtained with this method with the results gained from the ...

Map inference in the face of noise and disparity [PDF]
Proceedings of the 20th International Conference on Advances in Geographic Information Systems, 2012 This paper describes a process for automatically inferring maps from large collections of opportunistically collected GPS traces. In this type of dataset, there is often a great disparity in terms of coverage. For example, a freeway may be represented by thousands of trips, whereas a residential road may only have a handful of observations ...

A 3D Dust Map Based on Gaia, Pan-STARRS 1, and 2MASS [PDF]
Astrophysical Journal, 2019 We present a new three-dimensional map of dust reddening, based on Gaia parallaxes and stellar photometry from Pan-STARRS 1 and 2MASS. This map covers the sky north of a decl. of −30°, out to a distance of a few kiloparsecs.

Calpain small subunit homodimerization is robust and calcium‐independent
FEBS Letters, EarlyView.Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.

Logistic map driven by dichotomous noise [PDF]
Physical Review E, 1993 Bifurcation diagrams and invariant densities are computed and interpreted for a logistic map driven by dichotomous noise. Two deterministic limits are analyzed. Changes in the stability of such a system, when varying the correlation time of the noise, are numerically studied.
