A Technique for Evaluation of CCD Video-Camera Noise [PDF]
IEEE Transactions on Circuits and Systems for Video Technology, 2008 This paper presents a technique to identify and measure the prominent sources of sensor noise in commercially available charge-coupled device (CCD) video cameras by analysis of the output images. Noise fundamentally limits the distinguishable content in an image and can significantly reduce the robustness of an image processing application.

Noise-Aware Video Saliency Prediction [PDF]
Proceedings of the British Machine Vision Conference 2021, 2021 We tackle the problem of predicting saliency maps for videos of dynamic scenes. We note that the accuracy of the maps reconstructed from the gaze data of a fixed number of observers varies with the frame, as it depends on the content of the scene. This issue is particularly pressing when a limited number of observers are available.

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 ...
