@graspergazon, @berak, usually we try to introduce a new model not only in samples but in tests too. In example, https://github.com/opencv/opencv/blob/master/modules/dnn/test/test_backends.cpp . You may find corresponding .prototxts at https://github.com/opencv/opencv_extra/tree/master/testdata/dnn and .caffemodel links at https://github.com/opencv/opencv_extra/blob/master/testdata/dnn/download_models.py .
