RD-Cost Regression Speed Up Technique For vvc intra block Partitioning
Research Paper / ICASSP / Apr 2024 / ["Compression", "Video coding", "Machine learning/ Deep learning /Artificial Intelligence"]

"The last standard Versatile Video Codec (VVC), aims to im- prove the compression efficiency by saving around 50% of bitrate at the same quality compared to its predecessor High Efficiency Video Codec (HEVC). However, this comes with a significant rise in computational complexity due to the new added tools in the encoder side. This paper proposes a speed- up technique to accelerate the partitioning process in VVC based on multi-output regression model that predicts a suit- able split mode for coding unit (CU) of size 32 × 32. Expire- ment results shows that our approach can reduce the complex- ity up to 43% with 0.96% BD-rate loss."

Low-Complexity Transform Design Using Hybrid Intra MTS
RESEARCH PAPER / Jun 2024 / ["Compression", "Video coding"]
In recent video coding standards, the introduction of multiple transform selection (MTS) has significantly improved coding efficiency. The latest standard, Versatile Video Coding (VVC), adopted implicit MTS as an alternative tool to explicit MTS. This tool reduces the encoder complexity by inferring the optimal transform type from decoder-side information instead...
Reducing the Complexity of Normalizing Flow Architectures for Point Cloud Attribute Compression
RESEARCH PAPER / Apr 2024 / ["Compression", "Volumetric Imaging", "Machine learning/ Deep learning /Artificial Intelligence"]
"Learning-based point cloud (PC) compression is a promising research avenue to reduce the transmission and storage costs for PC applications. Existing learning-based methods to compress PCs attributes employ variational autoencoders (VAE) or normalizing flows (NF) to learn compact signal representations. However, VAEs leverage a lower-dimensional bottleneck that limit the maximum...
Variable-Rate Learned Image Compression with Multi-Objective Optimization and Quantization-Reconstruction Offsets
RESEARCH PAPER / Mar 2024 / ["Compression", "Machine learning/ Deep learning /Artificial Intelligence"]
Achieving successful variable bitrate compression with computationally simple algorithms from a single end-to-end learned image or video compression model remains a challenge. Many approaches have been proposed, including conditional auto-encoders, channel-adaptive gains for the latent tensor or uniformly quantizing all elements of the latent tensor. This paper follows the traditional...
