OpenCV for Secret Agents

I haven't read all of it but so far, it is a good intro to some the more advanced OpenCv features.

This book was given to me as a Christmas present, and I have really enjoyed the content and examples so far. There was an issue with one of the Python methods used for facial recognition in Chapter 3 that was related to a version change of OpenCV. I emailed the author regarding the issue, and his response was fantastic. Within two hours I received an email acknowledging the problem, and a fixed version of the chapter code was already posted to the book's website. That is great customer service to go along with a great book. Thank you!

It's really good

mostly python, poor quality.

Excellent book!
