This textbook provides students and users with the necessary knowledge to successfullyto successfully acquire and process image data. It is consistently taken into account that image acquisition and image processing are based on the same mathematical concepts. Great emphasis was placed to present the sometimes complex relationships both clearly and mathematically sound.The material in the 7th edition of this textbook, which has been successful since 1991, has been restructured.In line with the rapid development of image sensor technology, optics and image sensor technology, optics and the diverse methods of reconstructing the three-dimensional world from image data. The focus was placed on working out the basic concepts. This enables the reader tounderstand the initially confusing variety of image acquisition methods and learn how to use them optimally. Artificial intelligence methods have deliberately not been integrated into the book. Rather, this book contains the necessary knowledge about image acquisition and processing in order to apply machine learning methods to image analysis in the best possible way.

The sixth edition has been revised and extended. The whole textbook is now clearly partitioned into basic and advanced material in order to cope with the ever-increasing field of digital image processing. In this way, you can first work your way through the basic principles of digital image processing without getting overwhelmed by the wealth of the material and then extend your studies to selected topics of interest. Each chapter now includes exercises that help you to test your understanding, train your skills, and introduce you to real-world image processing tasks. An important part of the exercises is a wealth of interactive computer exercises, which cover all topics of this textbook. These exercises are performed with the image processing software heurisko, which is included on the accompanying CD-ROM. In this way you can get own practical experience with almost all topics and algorithms covered by this book. The complete hyperlinked text of the book is now available on the accompanying CD-ROM.

Predictions of our future climate vary greatly, with detailed forecasts still subject to debate. One key uncertainty is caused by the lack of our present knowledge of transport processes in the air-water interface, which poses the main transfer resistance between the oceans and atmosphere. Modeling and predictions of our global climate can only be improved by gaining a more complete understanding of the mechanisms involved in transporting energy, mass and momentum across the phase boundary.This monograph contains selected, peer-reviewed post-conference contributions of the International Workshop on Transport at the Air-Sea Interface, which took place at Heidelberg University from September 6-8, 2006. The workshop brought together leading scientists from around the world, bridged the gap between modeling and measurements, and sparked new ideas for novel simulation and experimental efforts. The focus of the monograph is on small scale processes directly at the interface and includes the topics:- Small-scale transport processes at the air-sea interface: surface divergence, microscale and largescale wave breaking, intermittency and rain-induced gas exchange- Novel measurement techniques including eddy correlation measurements, active and passive thermography, visualization of concentration fields by fluorescent dyes, profile measurements and visualization of flow fields by particle imaging velocimetry (PIV)- Modeling of the transport across the air-water interface and simulation of flow fields as well as concentration fields in the boundary layer- Parameterizations of the transfer process for global modeling

Image sequence processing is becoming a tremendous tool toanalyze spatio-temporal data in all areas of naturalscience. It is the key to studythe dynamics of of complexscientific phenomena. Methods from computer science and thefield of application are merged establishing newinterdisciplinary research areas.This monograph emerged from scientific applications and thusis an example for such an interdisciplinaryapproach. It isaddressed both to computer scientists and to researchersfrom other fields who are applying methods of computervision. The results presented are mostly from environmentalphysics (oceanography) but they will be illuminating andhelpful for researchers applying similar methods in otherareas.

The world we live in is a dynamic one: we explore it by moving through it, and many of the objects which we are interested in are also moving. Tra?c, for instance, is an example of a domain where detecting and processing visual motion is of vital interest, both in a metaphoric as well as in a purely literal sense. Visual communication is another important example of an area of science which is dominated by the need to measure, understand, and represent visual motion in an e?cient way. Visual motion is a subject of research which forces the investigator to deal withcomplexity;complexityinthesenseoffacinge?ectsofmotioninaverylarge diversity of forms, starting from analyzing simple motion in a changing envir- ment (illumination, shadows, . . . ), under adverse observation conditions, such as bad signal-to-noiseratio (low illumination, small-scaleprocesses, low-dosex-ray, etc. ), covering also multiple motions of independent objects, occlusions, and - ing as far as dealing with objects which are complex in themselves (articulated objects such as bodies of living beings). The spectrum of problems includes, but does not end at, objects which are not ‘bodies’ at all, e. g. , when anal- ing ?uid motion, cloud motion, and so on. Analyzing the motion of a crowd in a shopping mall or in an airport is a further example that implies the need to struggleagainsttheproblemsinducedbycomplexity.

This book constitutes the refereed proceedings of the 29th Symposium of the German Association for Pattern Recognition, DAGM 2007. It covers image filtering, restoration and segmentation, shape analysis and representation, categorization and detection, computer vision and image retrieval, machine learning and statistical data analysis, biomedical data analysis, motion analysis and tracking, stereo and structure from motion, as well as 3D view registration and surface modeling.
