If you want a smaller and cheaper book on computer vision, I recommend Concise Computer Vision (Klette, Springer).
It's remarkably complete for its size. The level of detail is just enough that you can refresh or understand a topic, without drowning you in equations. The referencing could be better, but the main papers are called out.
