The release notes for the OpenCV 3.0 Alpha say that it includes "Car detection using Waldboost, ACF by Vlad Shakhuro and Nikita Manovich". I haven't been able to find it thus far. I have found the functions for waldboost and acffeature in the opencv_contrib repository, but I haven't been able to find any implementations or any other mention of car detection anywhere else.
Does anyone else have any more information on car detection in OpenCV, or were the release notes just overstating the inclusion of Waldboost and ACF for the new release?
