Long Volumetric Video
Overview :
Long Volumetric Video is a novel technology for reconstructing long voxel videos from multi-view RGB footage. This technique effectively models long voxel videos using a new 4D representation method called Temporal Gaussian Hierarchy, addressing the issues of high memory consumption and slow rendering speeds associated with traditional dynamic view synthesis methods when processing long videos. Key advantages of this technology include low training costs, fast rendering speeds, and minimal storage requirements, making it the first technology capable of efficiently processing minute-scale voxel video data while maintaining high-quality rendering.
Target Users :
The target audience includes researchers and developers in the fields of video processing, computer graphics, and dynamic view synthesis. This technology is well-suited for them as it offers an efficient method for processing long video data, significantly reducing memory usage and enhancing rendering efficiency, which is particularly important for applications that require handling large amounts of video data.
Use Cases
Achieving real-time rendering of long voxel videos on the SelfCap dataset.
Demonstrating real-time rendering effects on the DNA-Rendering dataset.
Conducting real-time rendering demonstrations of long video sequences on the Sports dataset.
Features
? Compactly model long voxel videos using Temporal Gaussian Hierarchy.
? Implement effective and efficient dynamic modeling in regions with different speed variations.
? Obtain sparse spherical harmonic coefficients through gradient thresholds, ensuring compact storage while maintaining view-dependent effects.
? Support real-time rendering with industry-leading rendering quality.
? Handle long video sequences comprising thousands of frames for real-time rendering.
? Enable real-time demonstrations across multiple datasets, including SelfCap, DNA-Rendering, Sports, etc.
? Provide online demonstrations and framework code for renderers to facilitate user learning and utilization.
