内容简介:
This book leads the reader on a guided tour of the practical methods that can reveal the most important information in the digital images used for scientific, forensic and technical purposes, using richly illustrated examples that show the reader the step-by-step procedures for correcting problems in recorded images, enhancing the critical details, isolating objects and structures for measurement, and deriving the quantitative data useful for subsequent analysis. The emphasis in the book is on teaching by example, and providing visual comparisons of the various tools that can be applied, following the typical workflow needed to correct imaging defects, enhance details, isolate objects and structures, and perform measurements. The examples are purposely taken from a wide range of subjects, including various kinds of microscopy, medical imaging, forensic photography, and astronomy.
作者简介:
John Russ is a retired professor with 50+ years experience in imaging using a wide range of optical and other instruments for technical, scientific and forensic purposes. His particular interests involve the processing and analysis of the resulting images in order to extract information useful for characterizing quantifying, classifying, and identifying the objects and structures represented. The application of these techniques ranges from the microscopic to the astronomical, and includes the structures of engineering and textile materials, imaging of biological and medical images, forensic imagery, and more.
