Info

Luis Pedro Coelho is a Computational Biologist: someone who uses computers as a tool to understand biological systems. Within this large field, Luis works in Bioimage Informatics, which is the application of machine learning techniques to the analysis of images of biological specimens. His main focus is on the processing of large scale image data. With robotic microscopes, it is possible to acquire hundreds of thousands of images in a day, and visual inspection of all the images becomes impossible. Luis has a PhD from Carnegie Mellon University, which is one of the leading universities in the world in the area of machine learning. He is also the author of several scientific publications. Luis started developing open source software in 1998 as a way to apply to real code what he was learning in his computer science courses at the Technical University of Lisbon. In 2004, he started developing in Python and has contributed to several open source libraries in this language. He is the lead developer on mahotas, the popular computer vision package for Python, and is the contributor of several machine learning codes. I thank my wife Rita for all her love and support, and I thank my daughter Anna for being the best thing ever.
About the Reviewers Matthieu Brucher holds an Engineering degree from the Ecole Superieure d'Electricite (Information, Signals, Measures), France, and has a PhD in Unsupervised Manifold Learning from the Universite de Strasbourg, France. He currently holds an HPC Software Developer position in an oil company and works on next generation reservoir simulation. Mike Driscoll has been programming in Python since Spring 2006. He enjoys writing about Python on his blog at http://www.blog.pythonlibrary.org/. Mike also occasionally writes for the Python Software Foundation, i-Programmer, and Developer Zone. He enjoys photography and reading a good book. Mike has also been a technical reviewer for the following Packt Publishing books: Python 3 Object Oriented Programming, Python 2.6 Graphics Cookbook, and Python Web Development Beginner's Guide. I would like to thank my wife, Evangeline, for always supporting me. I would also like to thank my friends and family for all that they do to help me. And I would like to thank Jesus Christ for saving me.
