Lossless Seismic Data Compression using Adaptive Linear Prediction
نویسندگان
چکیده
This paper presents a comparison of adaptive linear pre-dictors as applied to the area of lossless compression of seismic waveform data. Three methods are explored: the normalize least-mean square (NLMS) algorithm, the gradient adaptive lattice (GAL) algorithm, and the recursive least squares lattice (RLSL) algorithm. When compared to standard linear prediction techniques, all three of these methods require little overhead, are more computation-ally eecient, and can be implemented using oating point techniques. With respect to a standard seismic database, the RLSL lter outperforms the other two methods in nearly all cases tested.

Lossless Compression of Seismic Data into Fixed-Length Packets
We present an algorithm to losslessly compress a sequence of integers. The intended application is to encode seismic data at nodes in a network of seismometers. The algorithm performs predictive compression, using adaptive linear filtering to predict sample values and encoding variable numbers of samples into fixed-length packets. To accommodate packet losses, the packets include sufficient ove...
متن کاملCONTEXT−BASED PREDICTIVE LOSSLESS CODING FOR HYPERSPECTRAL IMAGES (WedAmPO3)
A cluster−based lossless compression algorithm for hyperspectral images is presented. Clustering is carried out on the original data according to the vectors spectra, and it is used to set up multiple contexts for predictive lossless coding. Low−order predictions are performed using adaptive Linear Least Squares (LLS) estimations which exploit the additional information provided by clustering. ...
متن کاملImproved Forward-Adaptive Prediction for MPEG-4 Audio Lossless Coding
MPEG-4 Audio Lossless Coding (ALS) is a new addition to the suite of MPEG-4 audio coding standards. The ALS codec is based on forward-adaptive linear prediction, which offers remarkable compression even with low predictor orders. Nevertheless, performance can be significantly improved by using higher predictor orders, more efficient quantization and encoding of the predictor coefficients, and a...
متن کاملLinear-Prediction-Based Multi-resolution Approach for Lossless Image Compression
We design a linear-prediction-based multi-resolution approach for lossless image compression. The linear prediction technique computes the weighted differences between six neighboring pixel values to estimate the predicted pixel value. The prediction error is decomposed by a one-level integer wavelet transform to improve the prediction. The performance of the proposed approach is compared with ...
متن کاملLossless Audio Coding Using Adaptive Multichannel Prediction
Lossless audio coding enables the compression of digital audio data without any loss in quality due to a perfect reconstruction of the original signal. The compression is achieved by means of decorrelation methods such as linear prediction. However, since audio signals usually consist of at least two channels, which are often highly correlated with each other, it is worthwhile to make use of in...
