disney the researcher evolved An artificial intelligence system that makes it much easier to make actors look younger or older in a scene. Artists can also manually adjust effects to look as realistic as possible, but AI tools do most of the heavy lifting. can be processed. It is said that it takes only 5 seconds for the AI to apply the aging effect to one frame.
Reaging an actor is typically a costly and cumbersome process that requires artists to go through the scene frame by frame and manually change the character’s appearance. In the past, attempts have been made to automate the process using neural networks and machine learning. The Disney researchers said that while it might work well for still images, other systems “usually suffer from loss of facial identity, reduced resolution, and erratic results on subsequent video frames.” They claim their solution provides “the first practical, fully automated, production-ready method for reaging faces in video images.”
team wrote on paper It is impossible to train a FRAN (face re-aging network) neural network on a dataset of real people. To do that, we need a pair of images showing subjects at two known different ages with the same facial expression, pose, lighting, and background. Instead, researchers created a database of thousands of randomly generated faces. They re-aged these synthetic faces using existing machine learning aging tools, and he sent the results of that process to FRAN.
A neural network analyzes a photograph of the face, predicts which parts of the face will be affected by aging, and applies effects such as wrinkles and skin smoothness as layers on top of the original face.As gizmodo The researchers argue that this approach allows FRAN to re-age the performer’s identity and appearance, even as the head or face moves around or the lighting changes in the shot. Unlike other methods, FRAN also does not require an additional face-to-face step.
There are many reasons why Disney would want to develop such a tool. For example, it can reduce the workload of visual effects artists and speed up the process.In addition to helping to age actors up and down in large, unbudgeted productions, it may help keep budget balloons in check.
