How can I show the values from vision.Cas​cadeObject​Detector?

Previously I have made a program using the viola jones taken from vision.CascadeObjectDetector and the program been able to run well. But then I was asked by my lecturer to display each value of a primary key that is used by methods viola jones such as haar feature, integral image, adaboost learning and cascade classifier. How can I show these values if I build a program using vision.CascadeObjectDetector? I'm really need help to solve these problems

hello Alvindra, what i know about vision.CascadeObjectDetector is u can only change it's parameters like classification model, scale factor, merge threshold etc. To know the values of primary keys you have to do step by step implementation of Viola Jones, like extraction of features, formation of integral image, cascading of classifiers etc., then you will be getting these values. you should see the references given in 'Help' 'vision.CascadeObjectDetector', mainly following paper for step by step implementation :- Viola, Paul and Michael J. Jones, "Rapid Object Detection using a Boosted Cascade of Simple Features", Proceedings of the 2001 IEEE Computer Society Conference on Computer Vision and Pattern Recognition, 2001. Volume: 1, pp.511–518. Since, vision.CascadeObjectDetector is a combined packet of all these steps,u can't get it directly. This is what I know about your question.
