  • Patent number: 9792676
    Abstract: A system for background image subtraction includes a computing device coupled with a 3D video camera, a processor o£ the device programmed to receive a video feed from the camera containing images of one or more subject that include depth information. The processor, for an image: segments pixels and corresponding depth information into three different regions including foreground (FG), background (BG), and unclear (UC); categorizes UC pixels as FG or BG using a function that considers the color and background history (BGH) information associated with the UC pixels and the color and BGH information associated with pixels near the UC pixels; examines the pixels marked as FG and applies temporal and spatial filters to smooth boundaries of the FG regions; constructs a new image by overlaying the FG regions on top of a new background; displays a video feed of the new image in a display device; and continually maintains the BGH.

  • Patent number: 9654765
    Abstract: A system is disclosed for executing depth image-based rendering of a 3D image by a computer having a processor and that is coupled with one or more color cameras and at least one depth camera. The color cameras and the depth camera are positionable at different arbitrary locations relative to a scene to be rendered. In some examples, the depth camera is a low resolution camera and the color cameras are high resolution. The processor is programmed to propagate depth information from the depth camera to an image plane of each color camera to produce a propagated depth image at each respective color camera, to enhance the propagated depth image at each color camera with the color and propagated depth information thereof to produce corresponding enhanced depth images, and to render a complete, viewable image from one or more enhanced depth images from the color cameras. The processor may be a graphics processing unit.

  • Patent number: 9300946
    Abstract: A method, apparatus, system, and computer program product for of digital imaging. Multiple cameras comprising lenses and digital images sensors are used to capture multiple images of the same subject, and process the multiple images using difference information (e.g., an image disparity map, an image depth map, etc.). The processing commences by receiving a plurality of image pixels from at least one first image sensor, wherein the first image sensor captures a first image of a first color, receives a stereo image of the first color, and also receives other images of other colors. Having the stereo imagery, then constructing a disparity map and an associated depth map by searching for pixel correspondences between the first image and the stereo image. Using the constructed disparity map, captured images are converted into converted images, which are then combined with the first image, resulting in a fused multi-channel color image.

  • Patent number: 9053573
    Abstract: A color image and a depth image of a live video are received. A user is extracted from the information of the color image and the depth image. Spurious depth vales may be corrected. Points or pixels of an image as seen from a viewpoint of a reference camera at a reference camera location are mapped to points of the image as would be seen from a viewpoint of a virtual camera at a virtual camera location. As such, a transformed color image is generated. Disoccluded pixels may be processed to address any gaps within the transformed color image.

  • Patent number: 9008457
    Abstract: An RGB color image and an infrared intensity image of a live video are received. The RGB color image is converted to a colorspace image comprising a channel corresponding to a brightness value. Each pixel of the converted colorspace image is evaluated to determine whether the brightness channel of the pixel exceeds a threshold value. If the brightness channel of the pixel exceeds the threshold value, the infrared intensity value of a corresponding pixel from the infrared intensity image is mixed into the pixel's channel value that corresponds to brightness. The converted colorspace image is converted back to an RGB color image.

  • Patent number: 8818028
    Abstract: A color image and a depth image of a live video are received. Each of the color image and the depth image are processed to identify a foreground, background, and an unknown region band of the live video. The unknown region band may comprise pixels between the foreground and the background. Further processing is performed to segment the pixels of the unknown region band between the foreground and the background. As such, processing is performed on the unknown region band in order to provide an improved user foreground video.

  • Publication number: 20120065813
    Abstract: Disclosed herein are systems, methods, and non-transitory computer-readable storage media for controlling hardware on a remote spacecraft. A system practicing the method first identifies a piece of hardware on a remote spacecraft and a desired action for the piece of hardware and generates a command packet configured to instruct the piece of hardware to perform the desired action. The system then generates a container packet for transmission to the remote spacecraft and embeds the command packet within the container packet such that the remote spacecraft decodes the embedded packet to cause the piece of hardware to perform the desired action. Then the system can transmit the embedded packet to the remote spacecraft. Also disclosed herein is a robust, fault-tolerant memory module having strings of memory modules configured with a correction module to detect and correct errors. The memory module can maintain high reliability against severe radiation, mechanical, and thermal effects.
