Rethinking Bjøntegaard Delta for Compression Efficiency Evaluation: Are We Calculating It Precisely and Reliably?
Xinyu Hang, Shenpeng Song, Zhimeng Huang +3
For decades, the Bjøntegaard Delta (BD) has been the metric for evaluating codec Rate-Distortion (R-D) performance. Yet, in most studies, BD is determined using just 4-5 R-D data p…

SPC-NeRF: Spatial Predictive Compression for Voxel Based Radiance Field
Zetian Song, Wenhong Duan, Yuhuai Zhang +3
Representing the Neural Radiance Field (NeRF) with the explicit voxel grid (EVG) is a promising direction for improving NeRFs. However, the EVG representation is not efficient for…
