Resumo


This dissertation presents a machine learning-based solution to reduce the computational cost of compressing dynamic point clouds under the V-PCC standard. The proposed method employs decision models to accelerate the video encoding stage, which accounts for most of the processing. Results show an average 60% reduction in encoding time in Random Access mode, with minimal impact on coding efficiency (approximately 1.3% increase in BD-Rate), making the solution suitable for real-time applications and resource-constrained devices.
