Is there anywhere XML-files already trained to detection most popular objects?

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) * [gpu::HOGDescriptor::detectMultiScale](http://docs.opencv.org/modules/gpu/doc/object_detection.html#gpu-hogdescriptor-detectmultiscale) * [gpu::CascadeClassifier_GPU::detectMultiScale](http://docs.opencv.org/modules/gpu/doc/object_detection.html#gpu-cascadeclassifier-gpu-detectmultiscale)
