VideoCrafter2: Overcoming Data Limitations for High-Quality Video Diffusion Models [PDF]

Computer Vision and Pattern Recognition
Text-to-video generation aims to produce a video based on a given prompt. Recently, several commercial video models have been able to generate plausible videos with mini-mal noise, excellent details, and high aesthetic scores.

A Comparative Evaluation Of Temporal Pooling Methods For Blind Video Quality Assessment [PDF]

International Conference on Information Photonics, 2020
Many objective video quality assessment (VQA) algorithms include a key step of temporal pooling of frame-level quality scores. However, less attention has been paid to studying the relative efficiencies of different pooling methods on noreference (blind)

3D video quality metric for 3D video compression [PDF]

IVMSP 2013, 2013
As the evolution of multiview display technology is bringing glasses-free 3DTV closer to reality, MPEG and VCEG are preparing an extension to HEVC to encode multiview video content. View synthesis in the current version of the 3D video codec is performed using PSNR as a quality metric measure.

Implementation and evaluation of simultaneous video-electroencephalography and functional magnetic resonance imaging [PDF]

, 2010
The objective of this study was to demonstrate that the addition of simultaneous and synchronised video to electroencephalography (EEG)-correlated functional magnetic resonance imaging (fMRI) could increase recorded information without data quality ...

Spatio-Temporal Deformable Convolution for Compressed Video Quality Enhancement

AAAI Conference on Artificial Intelligence, 2020
Recent years have witnessed remarkable success of deep learning methods in quality enhancement for compressed video. To better explore temporal information, existing methods usually estimate optical flow for temporal motion compensation.

Towards a video quality assessment based framework for enhancement of laparoscopic videos [PDF]

Medical Imaging, 2020
Laparoscopic videos can be affected by different distortions which may impact the performance of surgery and introduce surgical errors. In this work, we propose a framework for automatically detecting and identifying such distortions and their severity ...

StyleGAN-V: A Continuous Video Generator with the Price, Image Quality and Perks of StyleGAN2 [PDF]

Computer Vision and Pattern Recognition, 2021
Videos show continuous events, yet most - if not all - video synthesis frameworks treat them discretely in time. In this work, we think of videos of what they should be - time-continuous signals, and extend the paradigm of neural representations to build
