UniAnimate: Taming Unified Video Diffusion Models for Consistent Human Image Animation
arXiv.orgRecent diffusion-based human image animation techniques have demonstrated impressive success in synthesizing videos that faithfully follow a given reference identity and a sequence of desired movement poses. Despite this, there are still two limitations:

A new equipment for the measurement of video noise
Radio and Electronic Engineer, 1971Describes a video noise measuring equipment which has been developed to meet the needs of a television broadcasting organization. The various measuring techniques available for this purpose are reviewed and the chosen method, which employs a sampling technique, is fully described.

Noise residual learning for noise modeling in distributed video coding
2012 Picture Coding Symposium, 2012Distributed video coding (DVC) is a coding paradigm which exploits the source statistics at the decoder side to reduce the complexity at the encoder. The noise model is one of the inherently difficult challenges in DVC. This paper considers Transform Domain Wyner-Ziv (TDWZ) coding and proposes noise residual learning techniques that take residues from ...

Noise parameter identification for video tracking systems [PDF]
Moscow University Mechanics Bulletin, 2017 The 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.

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

Media theory, it is no longer a novelty to say, has a problem with sound. Film and television theorists have, until recently, rarely set themselves the task of understanding the soundtrack, and even more rarely the does the problem of articulating sound and image come up.

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.

Perceptual Effects of Noise in Digital Video Compression
140th SMPTE Technical Conference and Exhibit, 1998We present results of subjective viewer assessment of video quality of MPEG-2 compressed video containing wide-band Gaussian noise. The video test sequences consisted of seven test clips (both classical and new materials) to which noise with a peak-signal-to-noise-ratio (PSNR) of from 28 dB to 47 dB was added.

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.
