      abstract     = {The inner surface of superconducting cavities plays a
                      crucial role to achieve highest accelerating fields. The
                      industrial fabrication of cavities for the European X-Ray
                      Free Electron Laser (EXFEL) and the International Linear
                      Collider (ILC) HiGrade Research Project allowed for an
                      investigation of this interplay with a large sample on
                      different cavities undergoing a standardized procedure. For
                      the serial inspection of the inner surface, the optical
                      inspection robot OBACHT was constructed and to analyze the
                      large amount of data, represented in the images of the inner
                      surface, an image processing and analysis code was
                      developed. New variables to describe the cavity surface were
                      obtained. Two approaches using these variables and images to
                      automatically detect defects has been implemented and
                      tested. In addition, a decision-tree based approach of
                      classifying defect free surfaces regarding their
                      accelerating performance was tested and found to be
                      physically valid.},
