From a bit stream, at least the following are decoded: a stereoscopic image of first and second views; a maximum positive disparity between the first and second views; and a minimum negative disparity between the first and second views. In response to the maximum positive disparity violating a limit on positive disparity, a convergence plane of the stereoscopic image is adjusted to comply with the limit on positive disparity. In response to the minimum negative disparity violating a limit on negative disparity, the convergence plane is adjusted to comply with the limit on negative disparity.

In one embodiment, a device maintains a predetermined number of high-priority subcarriers for use in communicating high-priority data frames and a predetermined number of low-priority subcarriers for use in communicating low-priority data frames. A data frame is received and a data frame priority is determined for the data frame. If the data frame is determined to be a low-priority data frame, a minimum number of subcarriers, from the low-priority subcarriers, required for communication of the data frame is determined and the data frame is communicated using the minimum number of subcarriers. If the data frame is determined to be a high-priority data frame, a maximum number of subcarriers available, including the high-priority subcarriers and the low-priority subcarriers, is determined and the data frame is communicated using the maximum number of subcarriers.

A method and apparatus for estimating stereo misalignment using modified affine or perspective model. The method includes dividing a left frame and a right frame into blocks, comparing horizontal and vertical boundary signals in the left frame and the right frame, estimating the horizontal and the vertical motion vector for each block in a reference frame, selecting a reliable motion vectors from a set of motion vectors, dividing the selected block into smaller features, feeding the data to an affine or a perspective transformation model to solve for the model parameters, running the model parameters through a temporal filter, portioning the estimated misalignment parameters between the left frame and right frame, and modifying the left frame and the right frame to save some boundary space.

In one embodiment, a Bloom filter is provided in a data packet signal functional to preferably encode the identifier of each nodal device and record the nodal hop count the signal traverses across in a computer network. The Bloom filter provided in a data packet signal has one or more fields. The recorded nodal path may updated en-route as the data packet traverses a nodal path in the computer network and/or the order of nodes traversed by the data packet in the computer network are encoded in the bloom filter.

In one embodiment, a battery-operated communication device “quick-samples” a frequency hopping sequence at a periodic rate corresponding to a substantially low duty cycle, and is discovered by (e.g., attached to) a main-powered communication device. During a scheduled sample, the main-powered communication device transmits a control packet to be received by the battery-operated communication device, the control packet containing timing information and transmitted to account for worst-case clock drift error between the two devices. The battery-operated communication device responds to the control packet with a link-layer acknowledgment containing timing information from the battery-operated communication device. Accordingly, the two devices may re-synchronize their timing based on the timing information in the control packet and acknowledgment, respectively.

In the present methods, the automatic detection of polyps is converted into a 2D pattern recognition problem using conformal mapping and direct volume rendering. The colon surface is first segmented and extracted from the CT data set of the abdomen, which is then mapped to a 2D plane using conformal mapping. Ray casting is used to determine sub-surface density values and the flattened image is rendered using a volume rendering technique with a translucent electronic biopsy transfer function. Polyp candidates are detected by a clustering method which identifies regions of elevated sub-surface density. The potential for false positives is reduced by analyzing the volumetric shape and texture features of the polyp candidate regions.

In one embodiment, a device receives and stores a broadcast schedule, and may determine whether a neighbor unicast listening schedule is available for a neighboring device. If so, the device may transmit a data frame to the neighboring device pursuant to the neighbor unicast listening schedule. If a neighbor unicast listening schedule is not available, the device may transmit the data frame to the neighboring device pursuant to a broadcast schedule. Once the data frame is received by the neighboring device, pursuant to the neighbor unicast listening schedule or the broadcast schedule, an acknowledgement may be received from the neighboring device, which may include an updated neighbor unicast listening schedule for that neighboring device.

A display-camera system includes a liquid crystal panel having a screen side and a back side that is opposed to the screen side. A visible light camera is positioned a first spaced distance from the back side such that a field of view of the camera encompasses all or a fraction of an area of the liquid crystal panel. A visible light source is positioned a second spaced distance from the back side and outside of the field of view of the camera. A diffuser is positioned between the visible light source and the back side.

Methods for automatic focus in a stereographic imaging device that includes two imaging sensor systems are provided. Focus searches are executed on both imaging sensor systems to determine optimal focused lens positions for each. The focus searches may be executed currently or sequentially, and may be at differing lens position granularities. Focal scores and spatial locations, i.e., the locations of focus regions, may be shared between the imaging sensor systems to coordinate the focus searches. Touchscreen coordinates may also be used to coordinate the focus searches.

In one embodiment, a device in a frequency hopping communication network operate in a first mode according to a common broadcast schedule for the network that simultaneously overlays a first configured portion of all independently determined unicast listening schedules in the network. In response to determining a power outage condition, the device switches to operation in a power outage mode where the common broadcast schedule for the network in the power outage mode simultaneously overlays a second configured portion of all independently determined unicast listening schedules in the network, the second configured portion greater than the first configured portion. In one embodiment, the device broadcasts one or more power outage notifications (PONs) in response to determining the power outage condition as a reduction of a main power supply at the device. In another embodiment, the device receives a PON while powered as the power outage condition.
