Abstract: Embodiments are directed towards determining within a digital camera whether a pixel belongs to a foreground or background segment within a given image by evaluating a ratio of derivative and deviation metrics in an area around each pixel in the image, or ratios of derivative metrics across a plurality of images. For each pixel within the image, a block of pixels are examined to determine an aggregate relative derivative (ARD) in the block. The ARD is compared to a threshold value to determine whether the pixel is to be assigned in the foreground segment or the background segment. In one embodiment, a single image is used to determine the ARD and the pixel segmentation for that image. Multiple images may also be used to obtain ratios of a numerator of the ARD, useable to determine an extent of the foreground.

Abstract: A system and method are disclosed for communicating coherency information between initiator and target agents on semiconductor chips. Sufficient information communication to support full coherency is performed through a socket interface using only three channels. Transaction requests are issued on one channel with responses given on a second. Intervention requests are issued on the same channel as transaction responses. Intervention responses are given on a third channel. Such an approach drastically reduces the complexity of cache coherent socket interfaces compared to conventional approaches. The net effect is faster logic, smaller silicon area, improved architecture performance, and a reduced probability of bugs by the designers of coherent initiators and targets.

Abstract: Apparatus and methods for implementing learning by robotic devices. Attention of the robot may be manipulated by use of a spot-light device illuminating a portion of the aircraft undergoing inspection in order to indicate to inspection robot target areas requiring more detailed inspection. The robot guidance may be aided by way of an additional signal transmitted by the agent to the robot indicating that the object has been illuminated and attention switch may be required. The robot may initiate a search for the signal reflected by the illuminated area requiring its attention. Responsive to detecting the illuminated object and receipt of the additional signal, the robot may develop an association between the two events and the inspection task thereby storing a robotic context. The context of one robot may be shared with other devices in lieu of training so as to enable other devices to perform the task.

Abstract: A method, apparatus, and manufacture for generating an HDR image is provided. An original image is received from an HDR interlaced sensor that includes at least two fields captured with different exposures. The fields are separated from each other to provide separate images, and each of the separate images is upscaled. Next, blending is performed on each of the upscaled separate images to generate a high-dynamic range image, and ghost identification is performed on the high-dynamic range image. Subsequently, detail identification is performed on the high-dynamic range image. The detail identification includes identifying areas in the non-ghost areas of the high-dynamic range image that have details, and modifying the high-dynamic image by replacing each of the areas identified to have details with the corresponding area from the original image.

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.
