In a joint project with Advanced U.S. Technology Group ( ATG) we are working on filtering and detection techniques for offensive and illegal images. This is a one-class image classification problem and thus closely related to the project on  Unsupervised One-class Image Classification.


The purpose of this work is two-fold. Our first goal is to reliably and quickly filter offensive images from large databases of images, for instance in order to prevent minors from being exposed to such images.


The second application is the automatic detection of illegal image content. In this project we work jointly with Swiss authorities. For example, we want to facilitate the work of police officers and prosecutors who have to search a suspect's storage device for illegal content.
