Any code examples in C++ for outdoor object detection using Neuronal Network or pattern recognition with Visual Camera?

Hi I was wondering if any code example in C++ of implementation of outdoor object (vehicle or aircraft door) detection/recognition using Neuronal Network or pattern recognition? I read couple of papers and saw some algorithms such as (http://papers.nips.cc/paper/5207-deep-neural-networks-for-object-detection.pdf) or (http://web.eecs.umich.edu/~honglak/cvpr15-cnn-detection.pdf) . I will appreciate some code examples in C++ implementing those algorithms or giving some instruction of implementation of the algorithms in C++ . Thanks
