Since these defects are only partially visible under certain illumination directions, one image doesn't provide enough information for a recognition task. A classification requires inspecting the surface under different illumination directions, which results in image series. The information is distributed along this series and can be extracted by merging the knowledge about the defect shape and light direction.Technology: general issuesbicsscclassificationdetectionilluminationimage seriesinvariant featuresTechnology: general issuesPérez Grassi Anaauth1323444BOOK9910346913303321Variable illumination and invariant features for detecting and classifying varnish defects3035563UNINA
