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

Noise aliasing in interline‐video‐based fluoroscopy systems
Medical Physics, 2002Video‐based imaging systems for continuous (nonpulsed) x‐ray fluoroscopy use a variety of video formats. Conventional video‐camera systems may operate in either interlaced or progressive‐scan modes, and CCD systems may operate in interline‐ or frame‐transfer modes.

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.

Improving the noise immunity of receiving video distorted white Gaussian noise
2016 International Siberian Conference on Control and Communications (SIBCON), 2016The method of a nonlinear three-dimensional filtering of the video images distorted by additive white Gaussian noise is considered. Improvement of noise immunity of reception of noisy images achieved through the effective use of statistical redundancy video-sequence. The method is used filtering theory of conditional Markov processes.

Noise Power Estimation for Effective De-Noising in a Video Encoder
Proceedings. (ICASSP '05). IEEE International Conference on Acoustics, Speech, and Signal Processing, 2005., 2006This paper presents a noise estimation algorithm using multiresolution motion estimation in a video encoder. Firstly, the motion estimator finds minimum block-matching errors at the finest resolution and the middle resolution for each macroblock. Secondly, if the minimum block-matching error at the finest resolution of a certain macroblock is less than

Video de-noising and parallel implementation for full HD video conferencing
2013 IEEE Third International Conference on Information Science and Technology (ICIST), 2013In this paper, we propose a new de-noising algorithm to handle the mixture of salt and pepper noise and Gaussian noise in videoconference. The algorithm detects the type of noise according to the human visual characteristics first, and then uses median filter to remove salt and pepper noise, and spatial-temporal adaptive filter to remove Gaussian noise.

Noise parameter identification for video tracking systems
Moscow University Mechanics Bulletin, 2017The appearance of noises in output records is analyzed for the following movement video tracking systems: Qualisys Oqus, Vicon Bonita, and ARTTRACK2. The static and kinematic noise components are distinguished and their parameters are proposed to identify by comparing with model movements.

Video Self-Adaptive Noise Reduction Algorithm
2013In digital video processing systems, studying an efficient noise reduction algorithm has become an important issue. As the noise is uncertain, so I hope to develop an algorithm that can adapt to different levels of noise. The temporal filter has the advantage of retaining the edge and details of a picture while the spatial filter has better abilities ...

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
