ExtremeTech came across PatchMatch, a new algorithm for structural image editing. The video dates from 2009 but the tools demonstrated in the clip are still quite impressive. Some of the technology is already used in Photoshop to power Adobe's content-aware fill in Photoshop CS5, so likely more features will arrive in future editions of Photoshop.
The video below gives pointers at some of what we could see in Photoshop CS6… or later versions. The video is based on a scientific paper entitled “PatchMatch: A Randomized Correspondence Algorithm for Structural Image Editing.” The algorithm highlighted in the video is not only intelligent, but it’s quite fast, designed with the full understanding that for day-to-day design work tools need to not only be effective, they also need to be computationally efficient. And the best part: PatchMatch is already used in Photoshop.
