  1. R. Chityala, S. Pudipeddi. Image Processing and Acquisition using Python. Boca Raton: Taylor and Francis. [amazon][publisher][sample chapters at reedwith.us]
This book provides readers with a sound foundation in both image acquisition and image processing—one of the first books to integrate these topics together. By improving readers’ knowledge of image acquisition techniques and corresponding image processing, the book will help them perform experiments more effectively and cost efficiently as well as analyze and measure more accurately. Long recognized as one of the easiest languages for non-programmers to learn, Python is used in a variety of practical examples.
