note that this book has some significant bugs (I remember specifically a faulty quadratic equation that I was stuck on), but I don't think you use this book for the code, which is pretty outdated. This book is useful as a reminder that things like photoshop are driven by algorithms, many of which are not rocket science but rather, fit in your pocket. One thing I particularly like about this book is that the author used photographs of his child that look super unhappy. After applying filters to them, she looks even more unhappy. It gives the book a dark and foreboding feeling. Anyway, I always show this book to my students (along with processes like saving a raw image and opening it in audacity as a sound file, the custom tool in photoshop) as a means of demystifying image processing.
