Real-time Adaptive Tone Mapping for Monitoring High Contrast Hemispherical Image Capture with the GPU

The exposure of high dynamic range scenes needs special attention to capture all details. A new method for a low dynamic monitoring preview of the local scene details is presented. We follow the idea of edge preserving nonlinear bilateral filtering instead of classic methods such as linear high pass filtering or histogram equalization. Real-time performance is achieved with a GPU implementation keeping the CPU free for other tasks.
