An Analytic Transform Kernel Derivation Method for Video Codecs
Applied Sciences, 2021 In the standardization of versatile video coding (VVC), discrete cosine transform (DCT)-2, discrete sine transform (DST)-7, and DCT-8 are regarded as the primary transform kernels.

Codec-Aware Video Delivery Over SDNs
, 2021 To guarantee quality of delivery for video streaming over software defined networks, efficient predictors and adaptive routing frameworks are required. We demonstrate an agent that predicts video quality of delivery metrics in a scalable way using a bespoke codec-aware learning model.

Zerotree-based stereoscopic video CODEC [PDF]
Optical Engineering, 2005 Due to the provision of a more natural representation of a scene in the form of left and right eye views, a stereoscopic imaging system provides a more effective method for image/video display. Unfortunately the vast amount of information that must be transmitted/stored to represent a stereo image pair/video sequence, has so far hindered its use in ...

DRASIC: Distributed Recurrent Autoencoder for Scalable Image Compression
, 2019 We propose a new architecture for distributed image compression from a group of distributed data sources. The work is motivated by practical needs of data-driven codec design, low power consumption, robustness, and data privacy. The proposed architecture,

Division-Free Multiquantization Scheme for Modern Video Codecs
Advances in Multimedia, 2012 The current trend of digital convergence leads to the need of the video encoder/decoder (codec) that should support multiple video standards on a single platform as it is expensive to use dedicated video codec chip for each standard. The paper presents a

HEVC Based Mixed-Resolution Stereo Video Codec [PDF]
IEEE Access, 2018 This paper presents a High Efficiency Video Codec (HEVC) based spatial mixed-resolution stereo video codec. The proposed codec applies a frame interleaving algorithm to reorder the stereo video frames into a monoscopic video. The challenge for mixed-resolution video coding is to enable the codec to encode frames with different frame resolutions.
