View synthesis aims to create new views of a specific subject starting from a number of pictures taken from given point of views.
Currently a study branch of Computer Science Research, Vision Research and Artificial Intelligence fields are involved in the definition of suitable approaches to the problem. See
Computer Vision
Computer vision is an interdisciplinary scientific field that deals with how computers can gain high-level understanding from digital images or videos. From the perspective of engineering, it seeks to understand and automate tasks that the hum ...
Example problem 1: Is to take a number of images of a specific subject, taken from a specific point with a specific camera orientation and setting, and then use that data to build a synthetic image that looks as if it was taken from a virtual camera that is placed at a different point and with the same settings.
Example problem 2: Two people interact through their computers, using a webcam. Try to render corrected images, as if taken from a virtual webcam positioned behind the application window.
This would solve the long-standing
Eye contact
Eye contact occurs when two people look at each other's eyes at the same time. In humans, eye contact is a form of nonverbal communication and can have a large influence on social behavior. Coined in the early to mid-1960s, the term came from ...
problem which is experienced in this environment. A double illusion is perceived by the users: each of them looks at each other's face, but neither of them get the proper feeling of it.
An example application of view synthesis is
Free viewpoint television
Free viewpoint television (FTV) is a system for viewing natural video, allowing the user to interactively control the viewpoint and generate new views of a dynamic scene from any 3D position.
The equivalent system for computer-simulated video is ...
