Abstract: System and method for substantially reducing an involvement of an applications processor in receiving data from a touchscreen display. In one aspect, the system includes a controller may be configured in an autonomous mode where it automatically measures the touchscreen display based configuration information received from the applications processor, determines notable events based on the measurement data, stores data and event identifiers related to the notable events in a memory, and sends a notification to the applications processor when event data is available In another aspect, the system includes a controller that filters user interactions events and transmits data related to only notable events to the applications processor. Because of the autonomous and event filtering operations of the touchscreen controller, there are substantially less communications between the controller and the applications processor. This improves the speed and efficiency of the applications processor.

Abstract: Apparatus and methods for partial evaluation of synaptic updates in neural networks. In one embodiment, a pre-synaptic unit is connected to a several post synaptic units via communication channels. Information related to a plurality of post-synaptic pulses generated by the post-synaptic units is stored by the network in response to a system event. Synaptic channel updates are performed by the network using the time intervals between a pre-synaptic pulse, which is being generated prior to the system event, and at least a portion of the plurality of the post synaptic pulses. The system event enables removal of the information related to the portion of the post-synaptic pulses from the storage device. A shared memory block within the storage device is used to store data related to post-synaptic pulses generated by different post-synaptic nodes. This configuration enables memory use optimization of post-synaptic units with different firing rates.

Abstract: A noise reduction apparatus for digital cameras is presented that includes groups of one or more connected non-linear filter units. Each of the filter unit groups are driven by decimated input image data at a different level of decimation and the output of at least one of these filter unit groups serves as one of a plurality of inputs to another filter unit group driven at a different decimation level. Filtered image data from one or more filter unit groups is adaptively combined in response to one or more image metrics related to one or more local regional image characteristics.

Abstract: The optimal configuration of a number of optional pipeline stages within the data paths of systems-on-chip is determined by application of a solver. The solver includes variables such as: the placement of modules physically within the floorplan of the chip; the signal propagation time; the logic gate switching time; the arrival time, after a clock edge, of a signal at each module port; the arrival time at each pipeline stage; and the Boolean value of the state of activation of each optional pipeline stage. The optimal configuration ensures that a timing constraint is met, if possible, with the lowest possible cost of pipeline stages.

Abstract: A system, method, and computer program product for saturation insensitive weighted prediction coefficients estimation for video coding. The saturated pixels in frames of an input video are excluded from consideration in estimating weighted prediction coefficients that are then used to encode the input video. The saturated pixels include those having luma and/or chroma values above or below limits, and may be identified by use of a histogram. The saturated pixels may also be found by analyzing a lower resolution version of the frames, and/or sampling pixels in the frames. Embodiments enable improved video quality for a given bit rate, and increased coding efficiency, particularly for input video including frames with rapid pixel value changes. Separate portions of the frames may be processed separately, and the embodiments may execute within an optimization loop that minimizes a predetermined error function. The encoding format may include the H.264/AVC standard.

Abstract: A simple format is disclosed and referred to as Elementary Network Description (END). The format can fully describe a large-scale neuronal model and embodiments of software or hardware engines to simulate such a model efficiently. The architecture of such neuromorphic engines is optimal for high-performance parallel processing of spiking networks with spike-timing dependent plasticity.

Abstract: Embodiments are directed towards automatically creating a cinemagraph on at least an imaging device, where the cinemagraph can be created without additional user interaction beyond capturing an initial sequence of images, and indicating that a cinemagraph is to be created from the sequence. Automatic creation of the cinemagraph includes selecting an anchor frame within the sequence and aligning the other frames to the anchor frame. Detection and segmentation of moving objects within the sequence, with respect to the anchor frame are performed. A mask is generated and refined. Segmentation of masks are then unified, and combined with a background from the anchor frame to generate an animated sequence.

Abstract: A system, method, and computer program product for selecting qualifying frames from an image sequence for use in subsequent stitching into a composite panoramic image are disclosed. Incoming frames from any source may be cropped and downscaled prior to evaluation against qualifying criteria relating to image overlap and local motion. Qualifying images are saved and/or output. The resulting panoramic image generally uses fewer qualifying images and appears smoother and has fewer artifacts than those of the prior art. The qualifying criterion for image overlap is a predetermined overlap margin or percentage between a current image and a previous image from the sequence. The qualifying criterion for image motion includes a maximum amount of local motion, often due to passing objects. The embodiments may process incoming images in real time or from stored sequences. Problems may trigger user warnings.
