The proposed method relies on a U-net network to identify the location and boundaries of the object and the possible defective areas present on it by performing a pixel-wise classification based on local curvatures and data modulation. Experiments were performed on a real industrial problem using four variations of the architecture. The results demonstrate that the method combining geometric and photometric information enables the identification of a wider variety of shape and texture imperfections, with the resulting segmentations closely correlated with the visual impact of the defects. In addition, several suggestions are presented for near-term industrial utilization. 1560-229X https://katalogoa.mondragon.edu/janium-bin/janium_login_opac.pl?find&ficha_no=161733 https://hdl.handle.net/20.500.11984/6938 Specular surfaces Defect detection Deflectometry Artificial Neural Networks Deflectometric data segmentation for surface inspection: a fully convolutional neural network approach
