Book Description
Hyperspectral Data Compression provides a survey of recent results in the field of compression of remote sensed 3D data, with a particular interest in hyperspectral imagery. Chapter 1 addresses compression architecture, and reviews and compares compression methods. Chapters 2 through 4 focus on lossless compression (where the decompressed image must be bit for bit identical to the original). Chapter 5, contributed by the editors, describes a lossless algorithm based on vector quantization with extensions to near lossless and possibly lossy compression for efficient browning and pure pixel classification. Chapter 6 deals with near lossless compression while. Chapter 7 considers lossy techniques constrained by almost perfect classification. Chapters 8 through 12 address lossy compression of hyperspectral imagery, where there is a tradeoff between compression achieved and the quality of the decompressed image. Chapter 13 examines artifacts that can arise from lossy compression.

Book Description
Satellite Data Compression covers recent progress in compression techniques for multispectral, hyperspectral and ultra spectral data. A survey of recent advances in the fields of satellite communications, remote sensing and geographical information systems is included. Satellite Data Compression, contributed by leaders in this field, is the first book available on satellite data compression. It covers onboard compression methodology and hardware developments in several space agencies. Case studies are presented on recent advances in satellite data compression techniques via various prediction-based, lookup-table-based, transform-based, clustering-based, and projection-based approaches. This book provides valuable information on state-of-the-art satellite data compression technologies for professionals and students who are interested in this topic. Satellite Data Compression is designed for a professional audience comprised of computer scientists working in satellite communications, sensor system design, remote sensing, data receiving, airborne imaging and geographical information systems (GIS). Advanced-level students and academic researchers will also benefit from this book.

Book Description
The main objective of this research is to design and implement novel spectral-spatial processing techniques for hyperspectral image analysis and applications. Although the high dimensionality of hyperspectral image data makes its transmission and storage difficult, the uncompressed data format is still preferred as it avoids compression loss which may degrade classification accuracy. In this thesis, a quality-assured lossy compression scheme based on a modified three dimensional discrete cosine transform is proposed. This novel technique is demonstrated to maintain the integrity of hyperspectral data without degrading the classification accuracy. Furthermore, this work has led to the creation of an effective spectral feature extraction technique which uses curvelet transform and singular spectrum analysis. In addition to this, an original classification framework which combines joint bilateral filtering and an improved sparse representation classifier is presented. Experimental results show that the proposed methodologies outperform most of the state-of-the-art feature extraction and classification techniques commonly employed in the hyperspectral community. This work also demonstrates that hyperspectral imaging combined with advanced signal processing is an effective technology for food quality control applications. For example, when applied to the challenge of performing hyperspectral imaging-based meat quality assessment, the techniques proposed in this work are shown to provide a more effective solution than conventional visible and near-infrared spectroscopic technology. Finally, this thesis provides the first set of results of assessing the quality of beef and lamb samples using an improved data regression technique. To sum up, the outcome of this thesis advances the hyperspectral imaging community by proposing several novel methodologies, and extensive experiments have been conducted to demonstrate their superiority.
