High-Precision Dynamic Traffic Noise Mapping Based on Road Surveillance Video
ISPRS International Journal of Geo-Information, 2022 High-precision dynamic traffic noise maps can describe the spatial and temporal distributions of noise and are necessary for actual noise prevention. Existing monitoring point-based methods suffer from limited spatial adaptability, and prediction model ...

Dynamic noise mapping: A map-based interpolation between noise measurements with high temporal resolution [PDF]
Applied Acoustics, 2016 Abstract Since the introduction of the Environmental Noise Directive, strategic noise mapping has been used as a tool for noise policy in many European countries. Although these strategic noise maps have their merits, they also have some shortcomings: accuracy in predicted noise levels in shielded or quiet areas is not very high, the maps fail to ...

Dynamic noise maps for Ljubljana airport
Proceedings of 10th SESAR Innovation Days, 2021 The main purpose of this research is to assess the impact of aircraft noise around an airport considering spatial and temporal variations in the population. The concept of dynamic airport noise mapping has been demonstrated on Ljubljana airport case study. Detailed population mobility information for Slovenia were retrieved from a survey.

Multi-Exposure Fusion of Gray Images Under Low Illumination Based on Low-Rank Decomposition
Remote Sensing, 2021 Existing multi-exposure fusion (MEF) algorithms for gray images under low-illumination cannot preserve details in dark and highlighted regions very well, and the fusion image noise is large. To address these problems, an MEF method is proposed.
