Evaluation of privacy in high dynamic range video sequences

Touradj Ebrahimi, Martin Rerabek, Lin Yuan

The ability of high dynamic range (HDR) to capture details in environments with high contrast has a significant impact on privacy in video surveillance. However, the extent to which HDR imaging affects privacy, when compared to a typical low dynamic range ...
