    Keywords : Deep Learning; Image Recognition; Classification; Defect Detection; Automation; Neural Networks; Convolutional Neural Networks; Phase-measuring Deflectometry;

    Abstract : In this thesis we conclude that convolutional neural networks, together with phase-measuring deflectometry techniques, can be used to create models which can detect and classify defects on painted surfaces very well, even compared to experienced humans. Further, we show which preprocessing measures enhances the performance of the models. READ MORE
