Video Coding Using 3D Dual-Tree Wavelet Transform
EURASIP Journal on Image and Video Processing, 2007 This work investigates the use of the 3D dual-tree discrete wavelet transform (DDWT) for video coding. The 3D DDWT is an attractive video representation because it isolates image patterns with different spatial orientations and motion directions and ...

Impact of Constant Rate Factor on Objective Video Quality Assessment
Advances in Electrical and Electronic Engineering, 2017 This paper deals with the impact of constant rate factor value on the objective video quality assessment using PSNR and SSIM metrics. Compression efficiency of H.264 and H.265 codecs defined by different Constant rate factor (CRF) values was tested.

HTTP adaptive streaming with media fragment URIs [PDF]
, 2011 HTTP adaptive streaming was introduced with the general idea that user agents interpret a manifest file (describing different representations and segments of the media); where-after they retrieve the media content using sequential HTTP progressive ...

A content-aware quantisation mechanism for transform domain distributed video coding [PDF]
, 2018 The discrete cosine transform (DCT) is widely applied in modern codecs to remove spatial redundancies, with the resulting DCT coefficients being quantised to achieve compression as well as bit-rate control. In distributed video coding (DVC) architectures

HEVC based Stereo Video codec [PDF]
2nd IET International Conference on Intelligent Signal Processing 2015 (ISP), 2015 Development of stereo video codecs in latest multi-view extension of HEVC (MV-HEVC) with higher compression efficiency has been an active area of research. In this paper, a frame interleaved stereo video coding scheme based on MVHEVC standard codec is proposed.

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
