LOCO-ANS: An Optimization of JPEG-LS Using an Efficient and Low-Complexity Coder Based on ANS

open access: yesIEEE Access, 2021
Near-lossless compression is a generalization of lossless compression, where the codec user is able to set the maximum absolute difference (the error tolerance) between the values of an original pixel and the decoded one.

ALP: Adaptive Lossless floating-Point Compression

open access: yesProc. ACM Manag. Data, 2023
IEEE 754 doubles do not exactly represent most real values, introducing rounding errors in computations and [de]serialization to text. These rounding errors inhibit the use of existing lightweight compression schemes such as Delta and Frame Of Reference (

Multiscale deep context modeling for lossless point cloud geometry compression [PDF]

open access: yes2021 IEEE International Conference on Multimedia & Expo Workshops (ICMEW), 2021
We propose a practical deep generative approach for lossless point cloud geometry compression, called MSVoxelDNN, and show that it significantly reduces the rate compared to the MPEG G-PCC codec. Our previous work based on autoregressive models (VoxelDNN
