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…
DynaQuant: Dynamic Mixed-Precision Quantization for Learned Image Compression
Youneng Bao, Yulong Cheng, Yiping Liu +4
Prevailing quantization techniques in Learned Image Compression (LIC) typically employ a static, uniform bit-width across all layers, failing to adapt to the highly diverse data di…
ShiftLIC: Lightweight Learned Image Compression with Spatial-Channel Shift Operations
