Abstract: In a system on chip SoC, a memory control unit connected between the memory unit and the processing unit controls access to the memory unit. An update request received or generated by the processing unit triggers an update operation which comprises appending an update enabling record to a sequence of update records in the log region, writing new program code to the memory unit, and appending an update completion record to a sequence of update records. Write access to the log region is disabled if a fault is detected in the SoC during the update operation.

Abstract: Images of foreground objects in a scene are generated by causing electromagnetic radiation to be emitted having a first spectral power distribution from a surface of a first foreground object, which is adjacent or at least partially obscured by a second foreground object. A first image of both of the first and second foreground objects is acquired while the first foreground object emits electromagnetic radiation with the first spectral power distribution. A second image of the first and second foreground objects is acquired while the first foreground object is not emitting electromagnetic radiation or is emitting electromagnetic radiation with a second spectral power distribution which is different to the first spectral power distribution. An alpha matte of the first and second foreground objects is generated based on a comparison of the first image and second image.

Abstract: Various embodiments provide methods and systems for users and business owners to share content and/or links to visual elements of a place at a physical location, and, in response to a user device pointing at a tagged place, causing the content and/or links to the visual elements of the place to be presented on the user device. In some embodiments, content and links are tied to specific objects at a place based at least in part upon one of Global Positioning System (GPS) locations, Inertial Measurement Unit (IMU) orientations, compass data, or one or more visual matching algorithms. Once the content and links are attached to the specific objects of the place, they can be discovered by a user with a portable device pointing at the specific objects in the real world.

Abstract: Systems and methods for displaying an image of a virtual object in an environment are described. A computing device is used to capture an image of a real environment including a marker. One or more virtual objects which do not exist in the real environment are displayed in the image based at least on the marker. The distance and orientation of the marker may be taken into account to properly size and place the virtual object in the image. Further, virtual lighting may be added to an image to indicate to a user how the virtual object would appear with the virtual lighting.

Abstract: Tracking hand or body pose from image data is described, for example, to control a game system, natural user interface or for augmented reality. In various examples a prediction engine takes a single frame of image data and predicts a distribution over a pose of a hand or body depicted in the image data. In examples, a stochastic optimizer has a pool of candidate poses of the hand or body which it iteratively refines, and samples from the predicted distribution are used to replace some candidate poses in the pool. In some examples a best candidate pose from the pool is selected as the current tracked pose and the selection processes uses a 3D model of the hand or body.

Abstract: A processor system includes at least two processor cores and an interrupt controller including interrupt priority registers configured for registering interrupt priorities of the respective processor cores. The processor system further includes at least two task timers associated with respective processor cores. Each task timer includes a counter configured for producing a counter value, a timeout value register configured for storing a timeout value and a tidemark value register configured for storing a tidemark value smaller than the timeout value. Each task timer is configured for producing a timeout signal when the counter value equals the timeout value and for producing a tidemark signal when the counter value equals the tidemark value. The interrupt controller is configured for increasing the interrupt priority of a processor core in response to a tidemark signal and for decreasing the interrupt priority of a processor core in response to a timeout signal.

Abstract: High frequency detection of interrupts includes incrementing a count by a first number in response to at least one interrupt. The count is decremented by a second number in response to a clock if the count is greater than zero. An interrupt rate is determined from the count. A fault collection unit (FCU) is updated when the interrupt rate exceeds a threshold.

Abstract: A method of sensing depth using an infrared camera. In an example method, an infrared image of a scene is received from an infrared camera. The infrared image is applied to a trained machine learning component which uses the intensity of image elements to assign all or some of the image elements a depth value which represents the distance between the surface depicted by the image element and the infrared camera. In various examples, the machine line component comprises one or more random decision forests.

Abstract: Region of interest detection in raw time of flight images is described. For example, a computing device receives at least one raw image captured for a single frame by a time of flight camera. The raw image depicts one or more objects in an environment of the time of flight camera (such as human hands, bodies or any other objects). The raw image is input to a trained region detector and in response one or more regions of interest in the raw image are received. A received region of interest comprises image elements of the raw image which are predicted to depict at least part of one of the objects. A depth computation logic computes depth from the one or more regions of interest of the raw image.
