The Digital Emily Project uses advanced face scanning, character rigging, performance capture, and compositing to achieve one of the world's first photorealistic digital facial performances. The project scanned the geometry and reflectance of actress Emily O'Brien's face in 33 poses, showing different emotions, gaze directions, and lip formations in a light stage. These high-resolution scans-accurate to skin pores and fine wrinkles-became the basis for building a blendshape-based facial-animation rig whose expressions closely matched the scans. The blendshape rig drove displacement maps to add dynamic surface detail. A video-based facial animation system animated the face according to the performance in a reference video, and the digital face was tracked onto the video's motion and rendered under the same illumination. The result was a realistic 3D digital facial performance credited as one of the first to cross the "uncanny valley" between animated and fully human performances.

The Digital Emily Project was a 2008 collaboration between facial animation company Image Metrics and the Graphics Laboratory at the University of Southern California's Institute for Creative Technologies to achieve one of the world's first photorealistic digital facial performances. The project leveraged latest-generation techniques in high-resolution face scanning, character rigging, videobased facial animation, and compositing. By building an animatable face model whose expressions closely mirror the shapes observed in a rich set of facial scans, acquiring realistic skin reflectance maps, and faithfully driving the face by video of an actual performance, the project rendered a synthetic facial performance which was generally mistaken to be a real face.
