Synthetic Defect Geometries of Cast Metal Objects Modeled via 2d Voronoi Tessellations
Natascha Jeziorski, Petra GospodnetiÄ, Claudia Redenbach
In industry, defect detection is crucial for quality control. Non-destructive testing (NDT) methods are preferred as they do not influence the functionality of the object while ins…
Simulation of microstructures and machine learning
Katja Schladitz, Claudia Redenbach, Tin Barisin +5
Machine learning offers attractive solutions to challenging image processing tasks. Tedious development and parametrization of algorithmic solutions can be replaced by training a c…
Sequential PatchCore: Anomaly Detection for Surface Inspection using Synthetic Impurities
Runzhou Mao, Juraj Fulir, Christoph Garth +1
The appearance of surface impurities (e.g., water stains, fingerprints, stickers) is an often-mentioned issue that causes degradation of automated visual inspection systems. At the…
SYNOSIS: Image synthesis pipeline for machine vision in metal surface inspection
Juraj Fulir, Natascha Jeziorski, Lovro Bosnar +6
The use of machine learning (ML) methods for development of robust and flexible visual inspection system has shown promising. However their performance is highly dependent on the a…
