Near lossless image compression system

2012 Asia Pacific Conference on Postgraduate Research in Microelectronics and Electronics, 2012
Image compression has become an important issue in relation to storage and transmission. A very simple and efficient near lossless image compression system is suggested in this paper. In the forward compression algorithm, image pixels are shifted right by the base value.

Near‐lossless compression methods for spectral images

Color Research & Application, 2011
AbstractIn this work, several near‐lossless compression methods for spectral images have been analyzed and compared. These methods are based both on the principal component analysis (PCA) and on the choice of a minimum number of spectral points, selected following different criteria.

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 REMOTE-SENSING DATA

2003
This paper describes data compression algorithms capable to preserve the scientific quality of remote-sensing data, yet allowing a considerable bandwidth reduction to be achieved. Unlike lossless techniques, by which a moderate compression ratio (CR) is attainable, due to the intrinsic noisiness of the data, and conventional lossy techniques, in which ...

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 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 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.
