Near-lossless compression of digital terrain elevation data
SPIE Proceedings, 2004In critical applications of image compression that are sensitive to information loss, lossless compression techniques are usually employed. The compression ratios obtained from lossless techniques are low. Hence we need different schemes that give quantitative guarantees about the type and amount of distortion incurred, viz.

Fixed-slope near-lossless context-based image compression
Proceedings 1998 International Conference on Image Processing. ICIP98 (Cat. No.98CB36269), 2002This paper generalizes trellis based near-lossless image compression schemes, in order to satisfy two constraints: a local one, which enforces an upper bound /spl epsiv/ for the reconstruction error at every pixel, and a global one, which penalizes the quantity R+/spl lambda/D (the rate and distortion over each line of the image).

ROI based near lossless hybrid image compression technique
2015 IEEE International Conference on Electrical, Computer and Communication Technologies (ICECCT), 2015Region of Interest based compression is an efficient method of compression for images with a particular part to be most significant. It is always a better choice to compress the ROI with lossless compression while the rest of image with lossy compression technique.

An improved low complexity Near Lossless Image Compression
International Journal of Signal and Imaging Systems Engineering, 2011In this paper, a new improved low complexity compression methodology named as Near Lossless Image Compression (NLIC) has been suggested. This algorithm is a hybrid method which includes DCT, a lossy compression technique and JPEG encoding using entropy based Huffman coding, a lossless compression technique.

Lossless and near-lossless compression of ECG signals
2001 Conference Proceedings of the 23rd Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2005We present a linear transformation algorithm (LTA), which is based on a new transformation, linear order transformation (LOT). Experimental results show that the LTA yields comparable results to the Burrows-Wheeler algorithm (BWA) and outperforms the Gzip, and shorten waveform coder for near-lossless ECG compression; for lossless ECG compression it ...

Near-lossless compression by relaxation-labeled 3D prediction
2000In this work, near-lossless compression, i.e., yielding strictly bounded reconstruction error, is proposed for high-quality data compression. An interframe causal DPCM scheme is presented for interframe compression of remotely sensed optical data, both multispectral and hyperspectral, as well as of volumetric medical data.

A method for progressive near-lossless image compression
Proceedings 2003 International Conference on Image Processing (Cat. No.03CH37429), 2004In this paper, we propose an algorithm, which allows for embedded coding in L/sub /spl infin// sense, i.e., progressive near-lossless as well as lossless image compression. The method is based on a lossy plus near-lossless refinement layered compression scheme. As a basis for the lossy layer we use the JPEG2000 standard.
