ALP: Adaptive Lossless floating-Point Compression
Proc. 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 (

HOW DOES SHANNON’S SOURCE CODING THEOREM FARE IN PREDICTION OF IMAGE COMPRESSION RATIO WITH CURRENT ALGORITHMS? [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2020 Images with large volumes are generated daily with the advent of advanced sensors and platforms (e.g., satellite, unmanned autonomous vehicle) of data acquisition. This incurs issues on the storage, processing, and transmission of images. To address such

Multiscale deep context modeling for lossless point cloud geometry compression [PDF]
2021 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

Learning Better Lossless Compression Using Lossy Compression [PDF]
Computer Vision and Pattern Recognition, 2020 We leverage the powerful lossy image compression algorithm BPG to build a lossless image compression system. Specifically, the original image is first decomposed into the lossy reconstruction obtained after compressing it with BPG and the corresponding ...

A Novel Rate Control Algorithm for Onboard Predictive Coding of Multispectral and Hyperspectral Images [PDF]
, 2014 Predictive coding is attractive for compression onboard of spacecrafts thanks to its low computational complexity, modest memory requirements and the ability to accurately control quality on a pixel-by-pixel basis.

Lossless Compression of Hexahedral Meshes [PDF]
Data Compression Conference (dcc 2008), 2008 Many science and engineering applications use high-resolution unstructured hexahedral meshes to model solid 3D shapes for finite element simulations. These simulations frequently dump the mesh and associated fields to disk for subsequent analysis, which involves the transfer of huge volumes of data.

Learning-Based Lossless Compression of 3D Point Cloud Geometry [PDF]
IEEE International Conference on Acoustics, Speech, and Signal Processing, 2020 This paper presents a learning-based, lossless compression method for static point cloud geometry, based on context-adaptive arithmetic coding. Unlike most existing methods working in the octree domain, our encoder operates in a hybrid mode, mixing ...
