This process, which NVIDIA calls image inpainting, can be used not only for restoring missing image pixels, but also for removing an unwanted object from a scene and filling it back in. If this sounds familiar, it's because Photoshop has been able to perform similar operations with Content-Aware Fill, which was introduced in the CS5 release. However, NVIDIA goes a step further given that inpainting was trained using 55,116 random streaks and holes to improve its performance. Another 25,000 were generated to further test the algorithm's accuracy. "Our model can robustly handle holes of any shape, size location, or distance from the image borders," wrote the NVIDIA researchers in a paper on inpainting.
