Abstract: In a remote interaction method performed by a remote collaboration system comprising a robot device and a head mounted display, the robot device is located in a remote space and comprising a projector, a panoramic camera and a high resolution camera. The head mounted display is located in a local space apart from the remote space. A communication between the robot device and the head mounted display is established based on a communication request. The remote space is observed by the head mounted display based on first image information and second image information. The first image information is collected by the panoramic camera and received from the robot device. The second image information is collected by the high resolution camera and received from the robot device. Necessary information to be provided to the remote space is searched by the head mounted display based on a result of observing the remote space. The necessary information received from the head mounted display is provided by the robot device to the remote space using the projector.

Abstract: Disclosed is a method for facial age simulation based on an age of each facial part and environmental factors, which includes: measuring an age of each facial part on the basis of an input face image; designating a personal environmental factor; transforming an age of each facial part by applying an age transformation model according to the age of each facial part and the environmental factor; reconstructing the image transformed for each facial part; and composing the reconstructed images to generate an age-transformed face. Accordingly, it is possible to transform a face realistically based on an age measured for each facial part and an environmental factor.
