I found ready treained XML-files only for face and its details (haarcascades), and for human body (HOG): https://github.com/Itseez/opencv/tree/master/data
Is there anywhere a (database) link to XML-files already trained to detection of different objects: cars, planes, people, animals, plants and other most popular objects?
I'm interested in the XML-files for both types: HOG and CascadeClassifier (haarcascades)
