Automatic Classification of Semi Precious Rocks

This project pretends to reach a successful model of automatic classification of semi precious rocks through Machine Learning techniques in TensorFlow and OpenCV image processing algorithms. Visual characteristics and image processing algorithms were proposed to correctly seg-ment the objects and identify their key features. After that, different TensorFlow models (DenseNet, NasNet, etc.) were tested to measure their accuracy and select the best method based on a comparative between performance and precision.
The results from the experiments were assessed and the definite algorithm was construct-ed. The algorithm runs on an Amazon Web Services instance, which is accessed by a mobile application. Results, scope and project limitations are discussed at the end of this work, as well as future approaches.
