Noise reduction in SEM video signals

International Journal of Electronics, 1976
Linear filtering methods of noise reduction in SEM video signals are discussed. It is shown that time-averaging filters distort and corrupt the signal to obtain optimum signal to noise ratio. Ensemble averaging filters are demonstrated as the better, since no signal distortion occurs.

UniAnimate: Taming Unified Video Diffusion Models for Consistent Human Image Animation

Science China Information Sciences
Recent 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:

ConsistI2V: Enhancing Visual Consistency for Image-to-Video Generation

Trans. Mach. Learn. Res.
Image-to-video (I2V) generation aims to use the initial frame (alongside a text prompt) to create a video sequence. A grand challenge in I2V generation is to maintain visual consistency throughout the video: existing methods often struggle to preserve ...

Compression noise based video forgery detection

2014 IEEE International Conference on Image Processing (ICIP), 2014
Intelligent video editing techniques can be used to tamper videos such as surveillance camera videos, defeating their potential to be used as evidence in a court of law. In this paper, we propose a technique to detect forgery in MPEG videos by analyzing the frame's compression noise characteristics.

Noise parameter identification for video tracking systems [PDF]

open access: possibleMoscow 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.

Magic-Me: Identity-Specific Video Customized Diffusion

ECCV Workshops
Creating content with specified identities (ID) has attracted significant interest in the field of generative models. In the field of text-to-image generation (T2I), subject-driven creation has achieved great progress with the identity controlled via ...

A Video-Frequency Noise-Spectrum Analyzer

Proceedings of the IRE, 1949
A 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.
