10. CONCLUSIONS: DPM model trained on the Image-Net dataset performed better than Steffi Morris’ manually annotated dataset. Likely due to the fact that Steffi’s dataset was much smaller (~150 vs ~1200) I believe that both datasets can be better annotated (include pose) to increase performance. DPM model I trained on the VOC2012 dataset performed ever so slightly better than the model pre-trained on the VOC2010 dataset Makes sense since the VOC2010 dataset is a subset of the VOC2012 dataset

11. GIS DATASETS: LOS ANGELES AND D.C. Found GIS data on fire hydrant, street lights, traffic lights and bus stops for the Los Angeles county Found GIS data for fire hydrants, metro entrances, bus stops, and AM/FM/Cell towers for Washington D.C. Final choice of dataset to use will depend on DPM results on metro stations, street lights and AM/FM/Cell towers, which I have doubts on how well they can be detected and the quality of the training dataset that can be found on these objects.
