    摘要: A method of enhancing spatial resolution of an image. An image is accessed. The image comprises a set of confident pixels and an unconfident pixel positioned adjacent to each confident pixel of the set of confident pixels. The set of confident pixels comprises four or fewer pixels and corresponds to a plurality of known depth values, the unconfident pixel comprises an unknown depth value. A best depth hypothesis for the unconfident pixel is determined using a filter module in which the plurality of known depth values are used as depth hypotheses. The unconfident pixel is updated as a confident pixel using the best depth hypothesis.

    摘要: 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.

    摘要: A projection system uses a transformation matrix to transform a projection image p in such a manner so as to compensate for surface irregularities on a projection surface. The transformation matrix makes use of properties of light transport relating a projector to a camera. A display pipeline of user-supplied image modification processing modules are reduced by first representing the processing modules as multiple, individual matrix operations. All the matrix operations are then combined with, i.e., multiplied to, the transformation matrix to create a modified transformation matrix. The created transformation matrix is then used in place of the original transformation matrix to simultaneously achieve both image transformation and any pre and post image processing defined by the image modification processing modules.

    摘要: Various embodiments of the present invention are directed to video-conferencing systems configured and operated to create eye contact between video conference participants. In one embodiment, video conferencing system includes a display, a video camera positioned to capture a video image of a first video conference participant through the display, and a projector positioned to project a video image of a second video conference participant onto the display screen such that the first participant can view the second participant. The display screen is positioned between the first participant and the video camera. The video camera and the projector can be operated during a video conference to establish eye contact between the first participant and the second participant by creating a line-of-sight that passes through a point of the head of the second participant's image between the video camera and the first participant.

    摘要: Producing high quality depth maps. A time of flight camera and stereo cameras of a stereo camera arrangement are mapped into a common coordinate system. A correspondence between an RGB image taken from the time of flight camera and an RGB image taken from a reference stereo camera of the stereo camera arrangement is established. Intensity values of the plurality of pixels of a stereo camera left of the reference stereo camera, a stereo camera right of the reference stereo camera and the reference stereo camera are determined. These intensity values of the stereo camera left of the reference stereo camera and the stereo camera right of the reference stereo camera are compared to the reference camera. Based on the comparing, matching intensity values are determined.

    摘要: Embodiments of the present invention are directed to a visual-collaborative system enabling geographically distributed groups to engage in face-to-face, interactive collaborative video conferences. In one aspect, a visual-collaborative system (400) comprises a display screen, a camera system, and a projector. The display screen (402) has a first surface (410) and a second surface (416), and the camera system is positioned to capture images of objects through the display screen. The projector (404,602,702) is positioned to project images onto the first surface that can be observed by viewing the second surface. The wavelengths of light used to produce the projected images are different from with the wavelengths of light used to capture images.
