DA-Lion: Efficient Neural Video Representation via Direction-Aware Optimization
Qingyu Mao, Jiacong Chen, Shuai Liu +2
Implicit neural video representation (NVR) encodes a video as the parameters of an overfitted neural network, where training and testing data are identical and the objective is ins…
Quality Assessment of 3D Gaussian Splatting: Distortions, Benchmarks, and Open Challenges
Shuai Liu, Binqiang Liu, Qingyu Mao +3
3D Gaussian Splatting (3DGS) has become a practical scene representation for real-time novel-view rendering, compression, and immersive content delivery. However, its quality asses…
Locality-Aware Density Control for Efficient Gaussian-based Image Representation
Jiacong Chen, Qingyu Mao, Xiandong Meng +5
2D Gaussian Splatting is an attractive direction for image representation due to its explicit formulation, fast rasterization, and favorable decoding efficiency. The representation…
STGV: Spatio-Temporal Hash Encoding for Gaussian-based Video Representation
Jierun Lin, Jiacong Chen, Qingyu Mao +4
2D Gaussian Splatting (2DGS) has recently become a promising paradigm for high-quality video representation. However, existing methods employ content-agnostic or spatio-temporal fe…
Motion Matters: Compact Gaussian Streaming for Free-Viewpoint Video Reconstruction
Jiacong Chen, Qingyu Mao, Youneng Bao +4
3D Gaussian Splatting (3DGS) has emerged as a high-fidelity and efficient paradigm for online free-viewpoint video (FVV) reconstruction, offering viewers rapid responsiveness and i…
Content-Distortion High-Order Interaction for Blind Image Quality Assessment
Shuai Liu, Qingyu Mao, Chao Li +4
The content and distortion are widely recognized as the two primary factors affecting the visual quality of an image. While existing No-Reference Image Quality Assessment (NR-IQA)…
