Noise reduction for video signals
2009Noise reduction is an important aspect of video processing. This thesis proposes a motion adaptive temporal-spatial noise reduction system. The three-step motion detection algorithm is the key for the system. First the pixel-to-pixel difference between two frames are compared to a threshold.

Noise level detection in general video
2018 International Workshop on Advanced Image Technology (IWAIT), 2018Noise level is a major factor when assessing the video quality. Although digital technologies have advanced, imaging is an analogue technology based on the photo-electric conversion imaging characteristics. Recently the sensitivity of imaging devices improved dramatically.

Temporal noise reduction of Bayer matrixed video data
Proceedings. IEEE International Conference on Multimedia and Expo, 2003This paper describes a new approach for noise reduction of video sequences that directly processes raw data frames acquired by an image sensor. The proposed noise reduction filter operates on Bayer matrixed video sequences instead of the canonical YUV format allowing saving of resources in terms of time and space; this is particularly relevant for real

A Video-Frequency Noise-Spectrum Analyzer
Proceedings of the IRE, 1949A wave analyzer capable of measuring noise spectra in the video-frequency range is described. Part I of the paper discusses requirements in noise-analyzer design. Part II is a detailed description of a practical instrument. A frequency range of 50 kc to 10 Mc is covered, without bandswitching, at virtually constant sensitivity.

Electronic equipment noise in video facilities
The Journal of the Acoustical Society of America, 1989Noise from electronic equipment is a significant problem for many video studios and ancillary facilities. Frequent efforts to control room ventilation noise are negated by noisy components that must be located within the critical spaces themselves. This paper will review acoustical design considerations for a few recent case histories.

Noise exposure of video games players
2019Video games are a leisure activity that is being practiced by more and more people. Even the average age of the users is gradually increasing, representing a pleasant activity for any age. The literature has widely insinuated the doubt whether such widespread use could have negative consequences for the health of its users. This article describes noise
