This paper presents a new approach allowing one or more projectors to display an undistorted image on a surface of unknown geometry. To achieve this, a single camera is used to capture the viewer’s perspective of the projection surface. No explicit camera and projector calibration is required since only their relative geometries are computed using structured light patterns. There is no specific...

This paper presents a device that creates ubiquitous interactive graphics in a real world environment without the need for pre-wiring surfaces or requiring users to carry or wear any special devices. Called the Everywhere Displays projector, or ED-projector, this device employs steerability as the key principle to achieve the promise of ubiquitous computing and augmented reality. The ED-project...

In this paper, we introduce a novel framework for automatic 3D facial expression editing in videos. The system can replace any kind of expression with another one smoothly in 3D videos. We build a 3D expression database to learn the expression space of a human face. The real-time 3D data were captured by a camera/projector scanning system. With this database, we acquire the geometry deformation...

This paper discusses a method for obtaining accurate 3D measurements using a temporally encoded structured light system. An objective of the work was to have a balance in the accuracy of all components in the system. This was achieved by including lens distortion in the models for both the camera and projector which comprise the structured light system. In addition, substripe estimation was use...

In this survey article we explain a few ideas behind the framework of the fermionic projector and summarize recent results which clarify the connection to quantum field theory. The fermionic projector is introduced, which describes the physical system by a collection of Dirac states, including the states of the Dirac sea. Formulating the interaction by an action principle for the fermionic proj...

This paper presents a novel method that leverages the stereo geometric relationship between projector and camera for absolute phase unwrapping on a standard one-projector and one-camera structured light system. Specifically, we use only one additional binary random image and the epipolar geometric constraint to generate a coarse correspondence map between projector and camera images. The coarse...

In this paper a new calibration method is proposed for projector using an uncalibrated camera. The difficulty to get a set of 2D-3D points in order to compute the projection matrix between the projector and the world has no easy solution. Methods are either inaccurate or inflexible. We propose an easy and automatic way to calibrate a projector. This method is a combination of pattern detection ...

We present a brief history of historic handheld projection devices and introduce design techniques for handheld projector interaction that draw from the principles of traditional animation and sequential art. Our approach is to utilize the movement of the handheld projector to express the motion and physicality of projected foreground objects. Users interact and control the projected image by m...
