Summary
This study introduces a fast decision mechanism for Versatile Video Coding (VVC) to optimize ternary tree (TT) partitioning. The method uses image features to predict optimal patterns, significantly speeding up encoding while maintaining quality.
Area of Science:
- Video compression technology
- Digital image processing
- Machine learning for video coding
Background:
- Versatile Video Coding (VVC) relies on complex coding unit (CU) partitioning for efficiency.
- Ternary tree (TT) partitioning in VVC intra coding is computationally intensive due to rate-distortion cost calculations.
- Current methods for optimal CU partition selection are time-consuming, hindering real-time applications.
Purpose of the Study:
- To develop a fast decision mechanism for VVC's ternary tree (TT) partitioning in intra coding.
- To reduce the computational complexity associated with rate-distortion optimization (RDO) for CU partitioning.
- To enhance overall video encoding efficiency without compromising visual quality.
Main Methods:
- Investigated the correlation between image structural features and TT partition patterns.
- Developed an efficient scheme for feature representation and extraction to minimize computational load.
- Constructed comprehensive datasets for training a predictive model for optimal TT partition selection.
- Integrated a predictive model into the VVC Test Model (VTM) for pre-RDO feature analysis.
Main Results:
- The proposed mechanism effectively predicts optimal TT partition patterns, enabling bypass of complex RDO calculations.
- Experimental results show significant time-saving improvements compared to existing lightweight neural network algorithms.
- The method achieved a favorable trade-off between prediction accuracy and model complexity.
- Coding quality was preserved while substantially accelerating the video coding process.
Conclusions:
- The image feature-based decision mechanism offers a computationally efficient approach to VVC intra coding.
- This method significantly accelerates video encoding by intelligently skipping unnecessary TT partitioning computations.
- The approach demonstrates superior performance in time-saving metrics and Bjøntegaard Delta Bit Rate (BDBR) compared to prior lightweight methods.

10.0K
In humans, more than 80% of the genome gets transcribed. However, only around 2% of the genome codes for proteins. The remaining part produces non-coding RNAs which includes ribosomal RNAs, transfer RNAs, telomerase RNAs, and regulatory RNAs, among other types. A large number of regulatory non-coding RNAs have been classified into two groups depending upon their length – small non-coding RNAs, such as microRNA, which are less than 200 nucleotides in length, and long non-coding RNA...

The “tree of life” describes the evolution of life and the evolutionary relationships between organisms. The root of the tree is the common ancestor to all life on Earth. All other species radiate from this point, much like the branches of a tree. The numerous tips of these branches on the tree of life represent every living, or extant, species. Extinct species, which are species that no longer exist, can be found towards the center of the tree. Currently, these organisms, both...

Survival trees are a non-parametric method used in survival analysis to model the relationship between a set of covariates and the time until an event of interest occurs, often referred to as the "time-to-event" or "survival time." This method is particularly useful when dealing with censored data, where the event has not occurred for some individuals by the end of the study period, or when the exact time of the event is unknown.

Phylogenetic trees come in many forms. It matters in which sequence the organisms are arranged from the bottom to the top of the tree, but the branches can rotate at their nodes without altering the information. The lines connecting individual nodes can be straight, angled, or even curved.

The human bronchi and bronchial tree play a crucial role in the respiratory system, facilitating the exchange of oxygen and carbon dioxide. Let's delve into the intricate structure and functions of these respiratory components.
The trachea, commonly known as the windpipe, is a tube that connects the larynx (voice box) to the bronchi. At a point called the carina, it bifurcates into two primary bronchi. The right primary bronchus is wider, shorter, and more vertical than the left primary...

The Nursing Code of Ethics sets the ethical benchmark for the profession, and guides nurses in ethical analysis and decision making at the societal, organizational, and clinical levels. The code encompasses showing compassion and respect for the patient, their families, and communities in all circumstances while committing to providing patient-centered care. In addition, the code states that nurses must advocate for the patient by defending a cause or recommendation to protect their rights,...
