Abstract

Denoising video is an important task, especially for videos captured in dim lighting environments. The filtering of video in a volumetric manner with time as the third dimension can improve the results significantly. In this work a 3D bilateral filter for edge preserving smoothing of video sequences exploiting commodity graphics hardware is presented. A hardware friendly streaming concept has been implemented to allow the processing of video sequences of arbitrary length. The clear advantage of time-based filtering compared to frame-by-frame filtering is presented as well as solutions to current limitations for volume filtering on graphics hardware. In addition, a significant speedup over a CPU based implementation is shown.
