Improving Unsupervised Defect Segmentation by Applying Structural Similarity to Autoencoders

13 code implementations5 Jul 2018 Paul Bergmann, Sindy Löwe, Michael Fauser, David Sattlegger, Carsten Steger

Convolutional autoencoders have emerged as popular methods for unsupervised defect segmentation on image data.

Online Photometric Calibration for Auto Exposure Video for Realtime Visual Odometry and SLAM

no code implementations5 Oct 2017 Paul Bergmann, Rui Wang, Daniel Cremers

We further show that our calibration can improve the performance of a state-of-the-art direct visual odometry method that works solely on pixel intensities, calibrating for photometric parameters in an online fashion in realtime.
