Sommario/riassunto |
|
This book is an essential guide to the implementation of image processing and computer vision techniques, with tutorial introductions and sample code in Matlab. Algorithms are presented and fully explained to enable complete understanding of the methods and techniques demonstrated. As one reviewer noted, ""The main strength of the proposed book is the exemplar code of the algorithms."" Fully updated with the latest developments in feature extraction, including expanded tutorials and new techniques, this new edition contains extensive new material on Haar wavelets, Viola-Jones, bilateral fi |

Multilevel Governance at the University of Western Ontario and one of Canada's most distinguished political scientists. In Across Boundaries Young's former colleagues and students bring together contributions from his extensive network. These essays speak to Young's legacy while providing new insight into research in multilevel governance, secession, and political economy. |
