Neural Net built with the Purdue RVL-SLLL American Sign Language Database. Keras/TensorFlow backend with a C# library called TensorFlowSharp form Miguel De Icaza. Issues with that library caused the final leg of the project to fall through in the last hour.
The Neural Net is trained to recognize both A and B, as computation time became a huge issue when we were tweaking the model.
