Measure The Difference between Frames: Reconsidering The Evaluation Method in Dynamic Mesh Simplification
2023 IEEE 12th Global Conference on Consumer Electronics (GCCE)(2023)
Abstract
Along with the development of 3D multimedia technology, the standardization of 3D volumetric video compression is in progress. Considering there is no objective method to evaluate the dynamic mesh simplification task in 3D video compression, an evaluation system based on mesh registration is established in this study. By converting the tracked mesh from the previous frame into a vertex set, Cloud-to-Cloud and Cloud-to-Mesh Distance can measure the similarity between two meshes from adjacent frames. Mesh surface distance and nearest vertex distance are two metrics designed to assess the performance of dynamic mesh simplification algorithms accurately. The evaluation system is also beneficial to measure the effectiveness of the new dynamic mesh simplification algorithms from similar studies in the future.
