Disclosed are embodiments of systems and methods for identifying features using color information in an image. The image may be formed from one or more display images comprising color information and features or feature components. Because color information may be used to identify features, more than one feature or feature component may be displayed in a display image. Because a plurality of features may be identified in a calibration image, an image system, such as a projector-camera system, can reduce the number of display images needed to calibrate the system.

A method and system for compensating for a moving object placed between a projector and a projection scene is shown. The method/system dividing a movement pattern of the moving object into N discrete position states, and for each of said N position states determining a corresponding view projection matrix. While projecting an image within any of the N position states, multiplying a desired projection image by the corresponding view projection matrix.

Light distortion due to light noise or light scattering object in the path of a light beam from a projector to a camera's image sensor in projector-camera systems are mitigated, or eliminated, by a simple modification to a light transport matrix T. For each row in light transport matrix T, matrix entries along a common row are compared, and all but the highest valued entry in the row are zeroed out, i.e. nullified. It is preferred that an array and record notation be used in order to reduce the size of the light transport matrix T, and its modified version to two arrays.

Systems and methods for synthesizing a surround visual field of image related to an input image are described. In one embodiment, the surround visual field is displayed in an area partially surrounding or surrounding an input image being displayed. In an embodiment, this surround visual field may comprise a plurality of images selected from a database of still images and/or video images based upon a characteristic or characteristics that relate to the displayed input image.

A method enhances an output image of a 3D object. A set of input images are acquired of a 3D object. Each one of the input images is illuminated by a different one of a set of lights placed at different positions with respect to the 3D object. Boundaries of shadows are detected in the set of input images by comparing the set of input images. The boundaries of shadows that are closer to a direction of the set of lights are marked as depth edge pixels.

Visual feedback is provided to a local user of a remote collaboration system. While an image is being captured, it is recognized that content is being shared on a screen. A composite image is generated which includes a form of the image being captured and the shared content. The composite image is caused to be displayed on a remote screen. A variably semi-transparent image of at least a portion of the composite image or the image is generated and is rendered on a portion of the screen such that the variably semi-transparent image is overlaid on any of the shared content or another composite image displayed on the screen.

Methods, computer-readable media, and systems are provided for combining multiple video streams. One method for combining the multiple video streams includes extracting a sequence of media frames (224-1/224-2) from presenter (222-1) video and from shared digital rich media (222-2) video (340). The media frame (224-1/224-2) content is analyzed (226) to determine a set of space and time varying alpha values (228/342). A compositing operation (230) is performed to produce the combined video frames (232) based on the content analysis (226/344).

Embodiments of the present invention disclose a telepresence portal system. According to one embodiment, the telepresence portal system includes a host portal having a plurality of host transparent displays arranged to face different sides of a host user. Furthermore, each host transparent display is associated with an image capturing device for capturing different viewpoint images of the host user. A remote portal is in communication with the host portal and includes a plurality of remote transparent displays arranged to correspond with the positions of the host transparent displays. In addition, each remote transparent display renders a viewpoint image of the host user on the corresponding remote transparent display for view by at least one remote user.

Embodiments of the present invention are directed to visual-collaborative systems enabling geographically distributed groups to engage in face-to-face, interactive collaborative video conferences. In one aspect, a visual-collaborative system comprises a transparent display (402) having a first surface (410) and a second surface (412); and a camera system positioned to face the second surface. The display is configured to show images that can be viewed by looking at the first surface. The display is also configured to transmit light scattered off of objects facing the first surface. The light passes through the display and is captured by the camera.
