An image segmenter uses one or more techniques to accurately segment an image, including the use of a progressive flood fill to fill incompletely bounded segments, the use of a plurality of scaled transformations and guiding segmentation at one scale with segmentation results from another scale, detecting edges using a composite image that is a composite of multiple color planes, generating edge chains using multiple classes of edge pixels, generating edge chains using the plurality of scaled transformations, and/or filtering spurious edges at one scale based on edges detected at another scale.

One embodiment of the invention relates to a method of merging segments to form supersegments in an image. The image consists of a plurality of segments that are constituent portions of the image. At least one candidate segment(s) and at least one neighboring segment(s) for each candidate segment are identified. An error statistic for each pair, consisting of a candidate segment and a corresponding neighboring segment, is computed. A neighboring segment is determined that results in a smallest error statistic for a given candidate segment. A determination is also made as to whether the smallest error statistic is sufficiently small to merit merging of the corresponding pair of segments. The corresponding pair of segments is merged to create one supersegment. The supersegment is a new segment including all pixels formerly contained in one of the two segments that were merged.

Methods and apparatuses associated with multi-phase wireless handshaking. A user terminal enters handshaking with an access point. The access point may respond to an access request of the user terminal with an access assignment, and alternatively, with a message indicating an assignment will not be presently given. The handshaking process could then be completed at a later time.

A wireless communication device monitors a radio frequency (RF) resource for a signal from a remote terminal. The wireless communications device detects the absence of the signal in the monitored RF resource. If the signal is not present in the RF resource, the wireless communications device reallocates processing resources reserved to process the signal to process data from another remote terminal.

Embodiment of the present invention can be used to select random access channels to be assigned to user terminals. In one embodiment, the invention includes a base station receiving a signal from a second radio, the received signal containing information about the second radio, and selecting one or more channels to be used by the second radio for random access to the base station using the information about the second radio. Then the base station sends a signal to the second radio, the sent signal containing information about the selected one or more channels.

In one embodiment, the present invention comprises transmitting a broadcast burst in a broadcast channel from a base station of a radio communications system. The invention further comprises receiving a request burst from a user terminal, and transmitting a message burst from the base station to the user terminal from which the request was received. The message burst includes a description of the channels available on the radio communications system for receiving messages from user terminals.
