Artificial data for Image classification in industrial applications

Sammanfattning: Machine learning and AI are growing rapidly and they are being implemented more often than before due to their high accuracy and performance. One of the biggest challenges to machine learning is data collection. The training data is the most important part of any machine learning project since it determines how the trained model will behave. In the case of object classification and detection, capturing a large number of images per object is not always possible and can be a very time-consuming and tedious process. This thesis explores options specific to image classification that help reducing the need to capture many images per object while still keeping the same performance accuracy. In this thesis, experiments have been performed with the goal of achieving a high classification accuracy with a limited dataset. One method that is explored is to create artificial training images using a game engine. Ways to expand a small dataset such as different data augmentation methods, and regularization methods, are also employed.
