Lossless coding for progressive archival of multispectral images
نویسندگان
چکیده
In this paper, a nonlinear subband decomposition scheme with perfect reconstruction is proposed for lossless coding of multispectral images. The merit of this new scheme is to exploit efficiently both the spatial and the spectral redundancies contained in a multispectral image sequence. Besides, it is suitable for progressive coding, which constitutes a desirable feature for telebrowsing applications. Simulation tests performed on real scenes allow to assess the performances of this new multiresolution coding algorithm. They demonstrate that the achieved compression ratios are higher than those obtained with currently used lossless coders.

Multispectral image compression for spectral and color reproduction based on lossy to lossless coding
In this paper we propose a multispectral image compression based on lossy to lossless coding, suitable for both spectral and color reproduction. The proposed method divides a multispectral image data into two groups, RGB and residual. The RGB component is extracted from the multispectral image, for example, by using the XYZ Color Matching Functions, a color conversion matrix, and a gamma curve....
متن کاملLossless Compression of Multispectral Images Using Prediction and Golomb Rice Coding
Lossless compression algorithms of multispectral images are typically divided into two stages, a decorrelation stage and a coding stage. This work deals with the design of predictors for the decorrelation stage which are both fast and good. to achieve this, both spectral and spatial correlations are used for the predictor. The residuals between the predicted values and real values are calculate...
متن کاملLossless Region-based Multispectral Image Compression
In this paper we present a lossless coding scheme for multispectral images. The algorithm di ers from classical lossless approaches of multispectral image coding (1, 2, 3) in the fact that it is based on an independent coding of spectrally homogeneous regions. Regions that present a common multispectral signature are segmented. Then, spectral prediction is performed within these regions and nal...
متن کاملProgressive and lossless image coding using optimized nonlinear subband decompositions
In super high-de nition image applications such as medical image archival, progressive and lossless coding is required since any degradation in the decompressed image is unacceptable. Recently, nonlinear subband decompositions have received much attention as they provide very compact multiresolution representations and they allow exact reconstruction of the input image. Within this framework, w...
متن کاملLossless Compression of Multispectral Images using Spectral Information
Multispectral images are available for different purposes due to developments in spectral imaging systems. The sizes of multispectral images are enormous. Thus transmission and storage of these volumes of data require huge time and memory resources. That is why compression algorithms must be developed. A salient property of multispectral images is that strong spectral correlation exists through...
