Near-lossless compression of 3-D optical data

IEEE Transactions on Geoscience and Remote Sensing, 2001
In this work, near-lossless compression yielding strictly bounded reconstruction error is proposed for high-quality compression of remote sensing images. A classified causal DPCM scheme is presented for optical data, either multi/hyperspectral three-dimensional (3-D) or panchromatic two-dimensional (2-D) observations. It is based on a classified linear-

A progressive Lossless/Near-Lossless image compression algorithm

IEEE Signal Processing Letters, 2002
A novel image compression technique is presented that incorporates progressive transmission and near-lossless compression in a single framework. Experimental performance of the proposed coder proves to be competitive with the state-of-the-art compression schemes.

Hypergraphs for Near-lossless Volumetric Compression

Fourth International Conference on Information Technology (ITNG'07), 2007
A hypergraphs-based image representation is already used for 2D lossless image compression. In this paper we extend this hypergraph representation on 3D-image and we add an alpha-tolerance. This extended representation conducts to a generalisation of the HLC lossless compression algorithm (A. Bretto and and L.

Near-lossless compression of medical images

1995 International Conference on Acoustics, Speech, and Signal Processing, 2002
This paper studies the characteristic properties of a specific class of near-lossless image compression schemes which consists of a lossless coder followed by a uniform scalar quantizer. Three specific instances of such schemes are investigated; namely, differential pulse code modulation, hierarchical interpolation, and two-dimensional space-varying ...

Near-lossless compression of coherent image data

Proceedings 2001 International Conference on Image Processing (Cat. No.01CH37205), 2002
Near-lossless compression yielding strictly bounded reconstruction error, is extended to preserved the radiometric resolution of data produced by coherent imaging systems. A noncausal DPCM, based on the Rational Laplacian Pyramid (RLP), recently introduced by the authors for despeckling, is adjusted to this purpose. The baseband icon of the RLP is DPCM

Near-Lossless Compression of Mass Spectra for Proteomics

2007 IEEE International Conference on Acoustics, Speech and Signal Processing - ICASSP '07, 2007
Recent improvements in mass spectrometry (MS) technology led to an explosive amount of MS data collected and shared. A typical liquid chromatography/mass spectrometry (LC/MS) "image" from the instrument used in this study consists of 4 GB of data.

A Novel Near Lossless Image Compression Method

2019 IEEE International Symposium on Circuits and Systems (ISCAS), 2019
A novel near lossless image compression method is proposed in this paper. In the proposed method, a redundant representation of the image is firstly obtained by pixel level shifting and then partitioned into image blocks with the same size. Next, the image blocks are classified into smooth image blocks and non-smooth image blocks.
