## Training
Training was performed on labeled 300 x 300 pixel images that were chipped from the original 5978 x 7648 pixel aerial images from the [National Agriculture Imagery Program (NAIP) database](https://www.fsa.usda.gov/programs-and-services/aerial-photography/imagery-programs/naip-imagery/). Each image contained at least one wind turbine which was labeled using [LabelImg](https://github.com/tzutalin/labelImg). A few of the labeled images are shown below. In total, 488 images were used for training. This training set included wind turbines of different capacity, manufacturer, and design.
