Figure 1 : The bilateral grid enables edge-aware image manipulations such as local tone mapping on high resolution images in real time. This 15 megapixel HDR panorama was tone mapped and locally refined using an edge-aware brush at 50 Hz. The inset shows the original input. The process used about 1 MB of texture memory. Abstract We present a new data structure-the bilateral grid, that enables fast edge-aware image processing. By working in the bilateral grid, algorithms such as bilateral

We parallelize our algorithms on modern GPUs to achieve real-time frame rates on high-definition video. We demonstrate our method on a variety of applications such as image editing, transfer of photographic look, and contrast enhancement of medical images.
