New software pulls all the photos of a specific person from a collection of tagged photos, analyses them for similarity of expression and head position, and links them in an animated movie. The final product can turn a smile into a frown or show how a person has aged over time.
"We can easily summarise a person's life in photos," says Ira Kemelmacher-Shlizerman, a postdoctoral researcher at the University of Washington who led the study. One example shows a girl growing from birth to age 20 in 2 minutes.
For traditional morphing used in Jackson's music video, each photo needs to be carefully marked to ensure a smooth conversion. A mouth pixel on the first photo must remain a mouth pixel in the second. And the computer creates the moving transitions from one photo to the next.
This new software uses existing photos to transition between the two images. It chooses each photo in the animated sequence based on its similarity to the previous image, while moving incrementally toward the person's head position and facial expression in the final photo. With collection of several hundred or thousand images, there are to be plenty of shots that capture a range of expressions.
Kemelmacher-Shlizerman will present this work in a paper at SIGGRAPH (Special Interest Group on Graphics and Interactive Techniques), a conference in Vancouver, Canada, next week.
A version of this software is now available in Picasa, a photo-hosting site run by Google, as a feature called Face Movie. This application is simplified to speed playback and doesn't display the photos chronologically.Ramanaidu Daggubati, more popular known as Rana, is a Telugu film actor.
