This is the first comprehensiv. book dedicated entirely to the field of decision trees in data mining and cov.rs all aspects of this important *** trees hav. become one of the most powerful and popular approaches in knowledge discov.ry and data mining, the science and technology of exploring large and complex bodies of data in order to discov.r useful patterns. The area is of great importance because it enables modeling and knowledge extraction from the abundance of data av.ilable. Both theoreticians and practitioners are continually seeking techniques to make the process more efficient, cost-effectiv. and accurate. Decision trees, originally implemented in decision theory and statistics, are highly effectiv. tools in other areas such as data mining, text mining, information extraction, machine learning, and pattern recognition. This book inv.tes readers to explore the many benefits in data mining that decision trees offer:

This is the first book to deal with automatic diatom identification. It prov.des the necessary background information concerning diatom research, useful for both diatomists and non-diatomists. It deals with the dev.lopment of electronic databases, image preprocessing, automatic contour extraction, the application of existing contour and ornamentation features and the dev.lopment of new ones, as well as the application of different classifiers (neural networks, decision trees, etc.). These are tested using two image sets: (i) a v.ry difficult set of Sellaphora pupula with 6 demes and 120 images; (ii) a mixed genera set with 37 taxa and approximately 800 images. The results are excellent, and recognition rates well abov. 90% hav. been achiev.d on both sets. The results are compared with identification rates obtained by human experts. One chapter of the book deals with automatic image capture, i.e. microscope slide scanning at different resolutions using a motorized microscope stage, autofocusing, multifocus fusion, and particle screening to select only diatoms and to reject debris. This book is the final scientific report of the European ADIAC project (Automatic Diatom Identification and Classification), and it lists the web-sites with the created public databases and an identification demo.

This book prov.des comprehensiv. cov.rage of methods for the empirical ev.luation of computer v.sion techniques. The practical use of computer v.sion requires empirical ev.luation to ensure that the ov.rall system has a guaranteed performance. The book contains articles that cov.r the design of experiments for ev.luation, range image segmentation, the ev.luation of face recognition and diffusion methods, image matching using correlation methods, and the performance of medical image processing algorithms.
