摘要： The disclosure includes a system and method for distributing video segments of a video to one or more brokers based on topics and storing the video segments in a distributed commit log associated with the topics. A video processing application decomposes a video into fragments, groups the fragments into topics based on identifiers associated with the fragments, breaks the fragments into a sequence of segments, distributes the sequence of segments to one or more brokers based on the topics, and stores, by the one or more brokers, the sequence of segments associated with a topic in a distributed commit log while preserving a sequence order of the sequence of segments.

摘要： The disclosure includes a system and method for associating protection data to a video object and verifying the content and source of the video object based on the protection data. A video processing application receives, at a producer, a video object; computes, at the producer, a digital signature based on content of the first video object; adds, at the producer, identification information of the producer to the digital signature of the first video object, the producer being a source of the first video object; transmits the first video object along with the digital signature from the producer to a first consumer; and authenticates, at the first consumer, the content and source of the first video object based on the digital signature.

摘要： Systems and methods are presented that use light sensors and computing devices to compute the depth of an object using shuttered light pulses. In one embodiment, depth is determined as follows: A light emitter emits a pulse of light that is directed toward an object. The pulse is reflected off the object and travels toward a beam splitter. The beam splitter splits the reflected pulse into multiple pulses, with each pulse directed to a shuttered sensor with a different shutter location. The shuttered sensors measure the integrated intensity of the light, and these values are used to determine the depth of the object. A method is presented which calibrates a system that has an arbitrary number of shutters and enables the system to determine the depth of an object, even in the presence of ambient illumination and scattered light.

摘要： An apparatus and method employing principles of stereo vision for determining one or more orientation parameters and especially the second and third Euler angles θ, ψ of an elongate object whose tip is contacting a surface at a contact point. The apparatus has a projector mounted on the elongate object for illuminating the surface with a probe radiation in a known pattern from a first point of view and a detector mounted on the elongate object for detecting a scattered portion of the probe radiation returning from the surface to the elongate object from a second point of view. The orientation parameters are determined from a difference between the projected and detected probe radiation such as the difference between the shape of the feature produced by the projected probe radiation and the shape of the feature detected by the detector. The pattern of probe radiation is chosen to provide information for determination of the one or more orientation parameters and can include asymmetric patterns such as lines, ellipses, rectangles, polygons or the symmetric cases including circles, squares and regular polygons. To produce the patterns the projector can use a scanning arrangement or a structured light optic such as a holographic, diffractive, refractive or reflective element and any combinations thereof. The apparatus is suitable for determining the orientation of a jotting implement such as a pen, pencil or stylus.
