Abstract: Disclosed is a system and associated methods for dynamically rendering an image with varying detail that emulates human vision and that provides a dynamic resolution or level of detail at each layer of the image that is equal to or greater than the resolvable detail that can be detected by human vision within each layer. The system may adjust a non-linear function based on one or more of a display size, a display resolution, and a viewer distance from a display. The system may determine a dynamic resolution or level of detail for each layer of the image based on the adjusted non-linear function. The system may render the image data at or greater than the dynamic resolution or level of detail determined for each layer.

Abstract: Providing of relevant information to a responder is described. A responder system receives alert data identifying an incident location. Available relevant data for the incident location is stored in the responder system. When relevant data is not stored, relevant data for the incident location is obtained from an external data source and stored in the responder system. While proceeding to the incident location and based on the alert data and the relevant data, initial augmented reality information is prepared for presentation to a responder. Upon arriving at the incident location, second augment reality information is generated. Upon arriving within a localized area of the incident location, an IoT device operable within the localized area is identified and selected and a communications link therewith is established. First IoT device data is received from the selected IoT device, and based thereon third augmented reality information is generated.

Abstract: When rendering a frame, e.g. that is to be used for rendering subsequent frames to be rendered, two versions of the frame are rendered, wherein the first version of the frame is rendered in its entirety but only a portion of the second version of the frame is rendered. The rendered portion of the second version of the frame is compared to a corresponding rendered portion of the first version of the frame. When the comparison determines that the two portions of the two versions match, the frame is, e.g. used for rendering subsequent frames, but when the comparison determines the two portions of the two versions do not match, an error operation is performed.

Abstract: When performing anisotropic filtering when sampling a texture to provide an output sampled texture value for use when rendering an output in a graphics processing system, an anisotropy direction along which to take samples in the texture is determined by determining X and Y components of a vector of arbitrary length corresponding to the direction of the major axis of an assumed elliptical projection of the sampling point for which the texture is being sampled onto the surface to which the texture is being applied, and then normalising the determined X and Y vector components to provide X and Y components for a unit vector corresponding to the direction of the major axis of the elliptical footprint of the sampling point to be used as the anisotropy direction along which to take samples in the texture.

Abstract: Systems and methods are disclosed for identifying a dirty camera in a monocular camera comprising n cameras. For each of one or more cycles, a dirty counter variable for each of the n cameras is set to 0. For each of the n cameras, an image is captured from the camera and an image metric is determined for the image, e.g. brightness and/or contrast. If the image metric is 10% greater, or 10% less, than the image metric for any of the other n?1 cameras in the monocular camera, then that camera is determined to be dirty and a corrective action is taken, such as sending an alarm to an occupant the vehicle or initiating a cleaning operation. If the dirty condition persists for a camera that has been cleaned within a threshold period of time (i.e., recently), then an alarm is sent to an operator of the vehicle.

Abstract: A system to process images includes a light source configured to emit a first illumination pattern onto one or more first portions of a scene. The system also includes an image sensor configured to capture light reflected from the scene in response to the emitted first illumination pattern. The system also includes an optimizer configured to perform raytracing of the light reflected from the scene. The system further includes a processor operatively coupled to the optimizer. The processor is configured to determine a parameter of a surface of the scene based on the raytracing, cause the light source to emit a second illumination pattern onto one or more second portions of the scene based at least in part on the parameter of the surface, and refine the parameter of the surface of the scene based on additional raytracing performed on reflected light from the second illumination pattern.

Abstract: Examples described herein relate to a decompression engine that can request compressed data to be transferred over a memory bus. In some cases, the memory bus is a width that requires multiple data transfers to transfer the requested data. In a case that requested data is to be presented in-order to the decompression engine, a re-order buffer can be used to store entries of data. When a head-of-line entry is received, the entry can be provided to the decompression engine. When a last entry in a group of one or more entries is received, all entries in the group are presented in-order to the decompression engine. In some examples, a decompression engine can borrow memory resources allocated for use by another memory client to expand a size of re-order buffer available for use. For example, a memory client with excess capacity and a slowest growth rate can be chosen to borrow memory resources from.

Abstract: A graphics processing unit (GPU) of a processing system transmits pixel data for a frame to a display in a compressed burst, so that the pixel data is communicated at a rate that is higher than the rate at which the display scans out the pixel data to refresh the frame at a display panel. By transmitting pixel data for the frame in a compressed burst, the GPU shortens the time spent transmitting the pixel data and extends the time before the next frame of pixel data is to be transmitted. During the extended time before the next frame of pixel data is to be transmitted, the GPU saves power by placing portions of the processing system in a reduced power mode.

In response to a difference between the current measurement and any of the plurality of orientation data most recently received from the accelerometer exceeding a threshold, the computing device sends the current orientation data to the host device at a second data transfer frequency, and adjust content displayed on the display device based on the current orientation data received by the host device.
