Abstract: A system and method for recording, backing up, and authenticating footage from a dash cam or other video device comprises continuously synchronizing checksums from segments of video as they are recorded into rolling storage with an authentication server located remotely. Only metadata is uploaded until the video device experiences an interrupt event, at which point the last few rolling segments, as well as subsequent rolling segments until the termination of the interrupt event, are written to persistent storage and uploaded to the authentication server at the earliest opportunity. The metadata and video are encrypted with an asymmetric public/private key system enabling third parties to confirm, with the public key, that the metadata on the recording device and the authentication server match, and with the private key, download the video footage from the interrupt event.

Abstract: A combined video of a scene may be generated for applications such as virtual reality or augmented reality. In one method, a data store may store video data with a first portion having a first importance metric, and a second portion having a second importance metric, denoting that viewing of the first portion is more likely and/or preferential to viewing of the second portion. The subset may be retrieved and used to generate viewpoint video from a virtual viewpoint corresponding to a viewer's viewpoint. The viewpoint video may be displayed on a display device. One of storing the video data, retrieving the subset, and using the subset to generate the viewpoint video may include, based on the difference between the first and second importance metrics, expediting and/or enhancing performance of the step for the first portion, relative to the second portion.

Abstract: A combined video of a scene may be generated for applications such as virtual reality or augmented reality. In one method, a camera system may be oriented at a first orientation and used to capture first video of a first portion of the scene. The camera system may then be rotated to a second orientation and used to capture second video of a second portion of the scene that is offset from the first portion such that the first video and the second video each have an overlapping video portion depicting an overlapping portion of the scene in which the first portion and the second portion of the scene overlap with each other. The first and second portions may be combined together to generate the combined video, which may depict the first and second portions substantially without duplicative inclusion of the overlapping video portion.

Abstract: According to various embodiments, light-field image data may be processed so as to prevent, remove, and/or mitigate artifacts caused by previous processing steps. A light-field image may first be captured by a light-field camera. One or more processing steps may be applied to the light-field image to generate a processed light-field image having one or more artifacts. A flat white modulation light-field image may also be captured by the light-field camera. The same processing steps previously applied to the light-field image may be applied to the modulation light-field image to generate a processed modulation light-field image with the same artifacts. The artifacts may then be identified in the processed modulation light-field image to generate an identification of the artifacts. This identification may be used to identify the same artifacts in the processed light-field image, which may then be corrected to remove the artifacts to generate a corrected, processed light-field image.

Abstract: Depth information is determined for elements in a light field image, thus allowing for rapid display of visualization tools to communicate such depth information to a user. Depth of strong edges within the light field image is analyzed, providing improved reliability of depth information while reducing or minimizing the amount of computation involved in generating such information. Strong edges can be identified and analyzed by generating epipolar images, or EPIs, from the light field image. Local gradients are determined for pixels in the EPIs. The magnitude of the local gradient is used to determine a confidence as to whether depth can be reliably estimated from the gradient. The orientation of the gradient is used to determine the depth of a corresponding element of the scene. Suitable output is then generated based on the determined depths, for example to provide information and feedback to aid a user in capturing light-field images.

Abstract: A method of manufacturing an organic light emitting device by which a pixel defining layer can be easily formed. The method includes: forming a first electrode on a substrate; forming a photoresist layer to cover the first electrode; patterning the photoresist layer and forming a blocking layer so that the blocking layer is on a side of the first electrode opposite to a side facing the substrate; forming a pixel defining layer on the substrate to cover side ends of the first electrode; removing the blocking layer and exposing the side of the first electrode contacting the blocking layer; forming an intermediate layer including an organic light emitting layer on the side of the first electrode that is exposed by removing the blocking layer; and forming a second electrode on the intermediate layer.
