Sensors, 2023 This paper is dedicated to video coding based on a compressive sensing (CS) framework. In CS, it is assumed that if a video sequence is sparse in some transform domain, then it could be reconstructed from a much lower number of samples (called ...

VideoControlNet: A Motion-Guided Video-to-Video Translation Framework by Using Diffusion Model with ControlNet [PDF]
arXiv.org, 2023 Recently, diffusion models like StableDiffusion have achieved impressive image generation results. However, the generation process of such diffusion models is uncontrollable, which makes it hard to generate videos with continuous and consistent content ...

An adaptive Lagrange multiplier determination method for rate-distortion optimisation in hybrid video codecs [PDF]
International Conference on Information Photonics, 2015 This paper describes an adaptive Lagrange multiplier determination method for rate-quality optimisation in video compression. Inspired by the experimental results of a Lagrange multiplier selection test, the presented approach adaptively estimates the ...

Side-Information Generation for Temporally and Spatially Scalable Wyner-Ziv Codecs
EURASIP Journal on Image and Video Processing, 2009 The distributed video coding paradigm enables video codecs to operate with reversed complexity, in which the complexity is shifted from the encoder toward the decoder. Its performance is heavily dependent on the quality of the side information generated

A modified video codec for MBMS applications [PDF]
Proceedings of the 4th international conference on Mobile and ubiquitous multimedia - MUM '05, 2005 Multimedia Broadcast Multicast Service (MBMS) is currently being standardized by the 3GPP. The MBMS services will enable new class of applications with efficient use of spectrum. MBMS also poses a new set of requirements on video coding and delivery. In this paper we present a short overview of MBMS and a video codec designed for MBMS.

Evolutionary strategy based improved motion estimation technique for H.264 video coding
, 2006 In this paper we propose an improved motion estimation algorithm based on evolutionary strategy (ES) for H.264 video codec applied to video. The proposed technique works in a parallel local search for macroblocks.
