This book discusses innovative methods for mining information from images of plants, especially leaves, and highlights the diagnostic features that can be implemented in fully automatic systems for identifying plant species. Adopting a multidisciplinary approach, it explores the problem of plant species identification, covering both the concepts of taxonomy and morphology. It then provides an overview of morphometrics, including the historical background and the main steps in the morphometric analysis of leaves together with a number of applications. The core of the book focuses on novel diagnostic methods for plant species identification developed from a computer scientist's perspective. It then concludes with a chapter on the characterization of botanists' visions, which highlights important cognitive aspects that can be implemented in a computer system to more accurately replicate the human expert's fixation process. The book not only represents an authoritative guide to advanced computational tools for plant identification, but provides experts in botany, computer science and pattern recognition with new ideas and challenges. As such it is expected to foster both closer collaborations and further technological developments in the emerging field of automatic plant identification.

'A phenomenal thriller, meticulously plotted and brilliantly realised' Clare Mackintosh, Books of the Year It starts quietly enough. A tick tick ticking you can hear in your ear. Tinnitus, you think. It will pass. But it doesn't. It gets worse. And then you pass it on... Before you know it, it spreads. Elsewhere across the globe, it emerges: small outbreaks at first, but then suddenly it's a plague - and only days later it is already killing people. In an increasingly affected north London school, teacher Kit Chaplin is struggling to understand what he is witnessing.
