摘要： Injection of 3D metadata into a requested video is disclosed. An input video and associated metadata are received by a video hosting site. If the metadata indicates that the input video is a 3D video, the 3D video system extracts the accompanying 3D metadata and stores it in an intermediate format, which is independent of the 3D metadata format and video format of the input video. The 3D video system stores the received video in a standard 2D video format in a video database. Responsive to a video streaming request of the input video, the 3D video system determines the actual 3D metadata format based on the video format of the requested video, and injects a modified 3D metadata associated with the input video into the requested video.

摘要： Methods and systems related to the detection of 3-D video content are disclosed herein. Specifically, a video image file may be analyzed in order to determine if it contains 3-D stereoscopic video content. An assumption is made regarding the possible 3-D format of the video image file. The assumption could be that the video frame includes a left portion and a right portion where each portion contains respective stereoscopic image perspectives. Image analysis algorithms could be used to determine if the left and right portions are sufficiently similar to confirm the assumption. If so, an indication could be carried out that could include a change to metadata or a similar change to associated video image file information. If the left and right portions of the video frame are not sufficiently similar, another analysis may be performed to test a different 3-D file format assumption.

摘要： Disclosed herein are methods, devices, and non-transitory computer readable media that relate to stereoscopic image creation. A camera captures an initial image at an initial position. A target displacement from the initial position is determined for a desired stereoscopic effect, and an instruction is provided that specifies a direction in which to move the camera from the initial position. While the camera is in motion, an estimated displacement from the initial position is calculated. When the estimated displacement corresponds to the target displacement, the camera automatically captures a candidate image. An acceptability analysis is performed to determine whether the candidate image has acceptable image quality and acceptable similarity to the initial image. If the candidate image passes the acceptability analysis, a stereoscopic image is created based on the initial and candidate images.

摘要： Metadata for a set of files in a file system is stored in a client metadata database. In addition, a subset of content for the set of files in the client metadata database is stored in a client content database. The subset of content does not exceed a cache size that is less than a full size of the content in the set of the files. In response to a request, at least a portion of the content that is not already stored in the client content database is retrieved from a server content database, where the server content database is located remotely from the client device.

摘要： The process comprises first forming a non-homogeneous aqueous mixture of the low solubility particulate material in a closed aqueous solution formation area by combining the low solubility particulate material and water. Next, low shear forces are imparted to the non-homogeneous aqueous mixture of the low solubility particulate material. The aqueous solution of the low solubility particulate material and substantially all of the particulate material dust associated therewith are removed from within the closed aqueous solution formation area by exerting a partial vacuum on the aqueous solution of the low solubility particulate material from outside the formation area. The process can also include the step of imparting the high shear forces to the non-homogeneous aqueous mixture of the low solubility particulate material which both particularizes and conveys at constant volume the low solubility particulate material. In the process of this invention, the aqueous solution of the low solubility particulate material typically contains substantially no undissolved visible particles of the low solubility particulate material.
