Common to all DNA and protein array-based technologies is the necessity to analyze digital images of the scanned DNA array. The focus of Kamberova and Shah book is microarray image analysis-from theoretical and application perspective. The topic of microarray image processing is usually neglected due to the availability of various software tools for image processing. The focus of today microarray bioinformatics is data analysis. However, how can one be certain that the data obtained from a microarray experiment through the image analysis is of high quality? How can one perform data mining on data derived from different microarray technologies, where microarray images were analyzed with different image analysis softwares? This book addresses various questions related to microarray image processing.
