Opis

An introduction to the chemometric technique of multi-variate image analysis and its applications in chemistry. The technique provides the user with statistical data structure and geometrical structure elements from the measurement of physical and chemical interactions, and is applied in many areas of process control in the food, chemical and textile industries. The book begins by introducing the reader to the basic ideas and principles necessary for understanding later chapters, which include discussions of magnetic resonance imaging, principal component analysis, and the pre-processing and transformation of images. It includes multivariate treatment of images, discusses visualization of multivariate space and explains interactive strategies and their background calculations.

The quantity of visual information encountered experimentally by scientists across a wide range of fields has grown dramatically in recent years. As a result, the importance of dealing with multivariate data (data obtained by measuring a number of different quantities simultaneously) present in images has become much more important, and the requirement for techniques which are able to manage and analyse these data has become crucial for the practising scientist in many diverse disciplines. Multivariate Image Analysis gives the reader a sound understanding of the importance of, and the principles behind, multivariate image analysis. A short introduction to the image and its perception is followed by a discussion of some popular techniques of multivariate image formation, taken from fields such as microscopy, remote sensing and medical imaging. The principles behind one of the key multivariate techniques, principal components analysis, are thoroughly explained without going too far into the theory: The important concepts of residual visualization and local modelling are explained. Throughout, the power of the techniques discussed is demonstrated with the use of simple worked examples to illustrate the concepts, and more complex examples to indicate to the reader how a complete analysis would be carried out. The book is richly illustrated with colour images. Multivariate Image Analysis is of great interest to all those involved in the analysis of data contained in complex images. The techniques discussed are widely applicable, and are finding use in fields such as microscopy, satellite remote sensing, medical imaging, radiology, analytical chemistry, spectroscopy and astronomy.
