  • Patent number: 9961370
    Abstract: A method and apparatus for a three-dimensional encoding or decoding system incorporating view synthesis prediction (VSP) with reduced computational complexity and/or memory access bandwidth are disclosed. The system applies the VSP process to the texture data only and applies non-VSP process to the depth data. Therefore, when a current texture block in a dependent view is coded according to VSP by backward warping the current texture block to the reference picture using an associated depth block and the motion parameter inheritance (MPI) mode is selected for the corresponding depth block in the dependent view, the corresponding depth block in the dependent view is encoded or decoded using non-VSP inter-view prediction based on motion information inherited from the current texture block.

  • Patent number: 9912965
    Abstract: Methods and apparatus for stereoscopic image encoding and decoding are described. Left and right eye images are encoded following an entropy reduction operation being applied to one of the eye images when there is a difference between the left and right images of an image pair. Information about regions of negative parallax within the entropy reduced image of an image pair is encoded along with the images. Upon decoding a sharpening filter is applied to the image in an image pair which was subjected to the entropy reduction operation. In addition edge enhancement filtering is performed on the regions of the recovered entropy reduced image which are identified in the encoded image data as regions of negative parallax. Interleaving of left and right eye images at the input of the encoder combined with entropy reduction allows for efficient encoding, storage, and transmission of 3D images.

  • Patent number: 9794543
    Abstract: An information processing apparatus for processing stereo images of an object includes a disparity calculator to calculate a disparity of the stereo images. The disparity calculator includes an evaluation value calculator to calculate a correlation evaluation value in a search range set for the stereo images; an extreme value detector to detect an extreme value of the correlation evaluation value; a threshold setting unit to set a threshold range for the detected extreme value; a counting unit to count the number of the extreme value existing within the threshold range; and an updating unit to update the set threshold range to a new threshold range when a new extreme value indicating a higher correlation level of the disparity compared to the set threshold range is detected. The counting unit counts the number of the extreme value in a threshold range updated most recently in the search range.

  • Patent number: 9787970
    Abstract: The present invention concerns the field of stereoscopic photography devices and more precisely calibration thereof. The invention proposes a method for calibrating a stereoscopic photography device that calculates a set of correction parameters for the images. These parameters are classed according to an order of importance. The first-order correction parameters are estimated first, the second-order correction parameters secondly. Advantageously, the first-order parameters are refined by taking account of the estimation values of the second-order parameters. Advantageously, a measurement of the relevance of the scene is carried out before the actual calibration.

  • Patent number: 9781405
    Abstract: Systems and methods provide accurate pixel depth information to be applied to a single image taken by a single camera in generating a three-dimensional (3D) image. In particular, two or more images can be captured during, e.g., lateral movement of a camera to ascertain depth in a scene on a pixel level. Use of an optical image stabilization (OIS) system that can provide at least three axes of stabilization eliminates the variability associated with conventional systems that create problems with image registration. Further still, and because actual pixel depth information is being calculated rather than merely generating stereoscopic images to trick the eyes into perceiving depth, the pixel depth information that is calculated can be leveraged in other ways, such as for providing automated measurements merely by taking a picture of an object or scene.

  • Patent number: 9769462
    Abstract: A system and method for combining and/or displaying text with three-dimensional content. The system and method inserts text at the same level as the highest depth value in the 3D content. One example of 3D content is a two-dimensional image and an associated depth map. In this case, the depth value of the inserted text is adjusted to match the largest depth value of the given depth map. Another example of 3D content is a plurality of two-dimensional images and associated depth maps. In this case, the depth value of the inserted text is continuously adjusted to match the largest depth value of a given depth map. A further example of 3D content is stereoscopic content having a right eye image and a left eye image. In this case the text in one of the left eye image and right eye image is shifted to match the largest depth value in the stereoscopic image. Yet another example of 3D content is stereoscopic content having a plurality of right eye images and left eye images.

  • Patent number: 9769453
    Abstract: A method including determining an aggregate cost for pixels in a frame under construction; applying a disparity computation for the pixels in the frame under construction; and storing the frame in a memory. Determining the aggregate cost for the pixels in a frame under construction includes use of at least one previous aggregate cost for the pixels in a previous frame, where the aggregate cost is determined with use of edge-aware filtering and a minimum spanning tree (MST). The disparity computation includes use of a confidence based temporal filtering of disparities at least partially using a disparity computation for the pixels in the previous frame.

  • Patent number: 9756336
    Abstract: A method and apparatus for video encoding or decoding utilizing adaptive background residual prediction is disclosed. The present invention adaptively applies background residual prediction to a current block based on a selection decision. The coding block is split into one or more coding sub-blocks. A reference sub-block in a reference picture is located for a current coding sub-block of the current coding block according to a motion vector associated with the current coding block. A background reference sub-block in a background picture is located for the reference sub-block, where the background reference sub-block is at a first co-located location as the reference sub-block. The method then selects a first predictor or a second predictor to encode or decode the current sub-block based on a selection decision. The first predictor corresponds to the reference sub-block, and the second predictor is derived according to the reference sub-block and the background picture.

  • Patent number: 9754159
    Abstract: A spherical content capture system captures spherical video content. A spherical video sharing platform enables users to share the captured spherical content and enables users to access spherical content shared by other users. In one embodiment, captured metadata or video/audio processing is used to identify content relevant to a particular user based on time and location information. The platform can then generate an output video from one or more shared spherical content files relevant to the user. The output video may include a non-spherical reduced field of view such as those commonly associated with conventional camera systems. Particularly, relevant sub-frames having a reduced field of view may be extracted from each frame of spherical video to generate an output video that tracks a particular individual or object of interest.
