Peace and Blessing upon you,

Please, I want to know the difference between the cascade classifier for C++ and C API ?
I had a test code with both, and the one for C++ "CascadeClassifier" was very accurate while the other "cvHaarCascadeClassifier" got a very confusing detections and representations as well

Here are 2 sample images as a result for each classifier

The cvHaarCascadeClassifier - C API - :

The CascadeClassifier - C++ API - :

Note: I was working for mac_OSX on XCode , is there is a dependency that made the results differ !

I was on opencv version 2.4.2 , but it's not the main idea for sure ...

Internally they both do the same thing, but cvHaarCascadeClassifier is the C interface and cv::CascadeClassifier is the c++ interface. I am guessing that your cvHaarCascadeClassifier is having problems with some error in your image, perhaps something with wrong channels or data type. It should be practically the same as cv::CascadeClassifier.
