Edge-Preserving Decompositions for Multi-Scale Tone and Detail Manipulation
Posted by 3dnews on September 1, 2008
Researchers at the Hebrew University of Jerusalem in collaboration with Microsoft have developed a new method for enhancing details in an image at variable scales while avoiding visual artifacts. It also solves important issues with tone mapping operators when processing HDR images (i.e. halos). Make sure to watch the video demonstration. Many recent computational photography techniques decompose an image into a piecewise smooth base layer, containing large scale variations in intensity, and a residual detail layer capturing the smaller scale details in the image. In many of these applications, it is important to control the spatial scale of the extracted details, and it is often desirable to manipulate details at multiple scales, while avoiding visual artifacts.
