Project Title: Tunable VVC Frame Partitioning Based on Lightweight Machine Learning
#
Project Overview:
The project aims to enhance video coding efficiency through the development of an adaptive and tunable frame partitioning mechanism for Versatile Video Coding (VVC) using lightweight machine learning techniques. With the increasing demand for high-quality video streaming, it is crucial to optimize video compression without sacrificing performance. This project seeks to leverage machine learning algorithms to intelligently partition video frames, optimizing bitrate and improving compression efficiency while maintaining the fidelity of the video content.
#
Background:
Versatile Video Coding (VVC), established in recent years, is the latest video compression standard optimized for a plethora of applications such as streaming, video conferencing, and broadcasting. One of the key factors affecting VVC’s performance is its frame partitioning strategies, which determine how video content is divided into coding units.
Traditional approaches to frame partitioning are often static or heuristically determined, which may not adapt to the varying complexities of video scenes. As video content becomes more diverse and complex, there is a pressing need for more dynamic solutions. Lightweight machine learning approaches, capable of real-time operations with minimal computational overhead, provide a pathway to achieve this.
#
Objectives:
1. Develop a Tunable Frame Partitioning Algorithm: Design a machine learning-based algorithm that dynamically adapts the partitioning of video frames based on the content characteristics.
2. Implement Lightweight Models: Use lightweight machine learning models that can be trained on pre-encoded datasets without the need for substantial computational resources, ensuring compatibility with real-time encoding systems.
3. Evaluate Performance Metrics: Conduct a thorough analysis of the proposed methodologies against standard benchmarks in terms of compression ratio, subjective and objective quality metrics, and computational efficiency.
4. User-Configurable Parameters: Enable tunable parameters that allow users to adjust the partitioning strategy based on specific use cases (e.g., low latency, high quality).
#
Methodology:
1. Data Collection: Gather a diverse dataset of video sequences with varying complexity, motion attributes, and content types.
2. Feature Extraction: Identify and extract key features (e.g., motion vectors, texture complexity, brightness, and detail levels) from video frames that can significantly influence optimal partitioning decisions.
3. Model Development:
– Choose suitable lightweight machine learning algorithms (e.g., decision trees, support vector machines, or lightweight neural networks) for frame classification.
– Train models using the extracted features to predict optimal partitioning strategies.
4. Integration into VVC Framework: Develop an extension to the existing VVC encoder that integrates the machine learning model, allowing for real-time decision-making during the encoding process.
5. Performance Evaluation:
– Benchmark against existing partitioning methods using real-world video sequences.
– Measure improvements in bitrate reduction, quality retention, and computational efficiency.
6. User Testing and Feedback: Conduct workshops with potential end-users (e.g., streaming services, content creators) to gather feedback on configurability and performance.
#
Expected Outcomes:
– A robust, lightweight machine learning model for adaptive frame partitioning in VVC.
– Improved video encoding performance, evidenced through quantitative and qualitative metrics.
– Increased usability and flexibility, making partitioning strategies configurable to user needs.
– Contributions to academic and industry research that can influence the future direction of video compression techniques.
#
Future Work:
This project could potentially lead to extensions beyond VVC, including application of the developed techniques to other compression standards like HEVC or AV1. Additionally, exploring deep learning methods could be a pathway for further development and research.
