Abstract: An attribute is computed based on pixel intensities in an image of the real world, and thereafter used to identify at least one input for processing the image to identify at least a first maximally stable extremal region (MSER) therein. The at least one input is one of (A) a parameter used in MSER processing or (B) a portion of the image to be subject to MSER processing. The attribute may be a variance of pixel intensities, or computed from a histogram of pixel intensities. The attribute may be used with a look-up table, to identify parameter(s) used in MSER processing. The attribute may be a stroke width of a second MSER of a subsampled version of the image. The attribute may be used in checking whether a portion of the image satisfies a predetermined test, and if so including the portion in a region to be subject to MSER processing.

Abstract: Techniques for transmitting pilot and for processing received pilot to obtain channel and interference estimates are described. A terminal may generate pilot symbols for a first cluster in a time frequency block based on a first sequence and may generate pilot symbols for a second cluster in the time frequency block based on a second sequence. The first and second sequences may include common elements arranged in different orders and may be considered as different versions of a single sequence. The terminal may transmit the pilot symbols in their respective clusters. A base station may obtain received pilot symbols from multiple clusters in the time frequency block. The base station may form each of multiple basis vectors with multiple versions of the sequence assigned to the terminal and may process the received pilot symbols with the multiple basis vectors to obtain a channel estimate for the terminal.

Abstract: An electronic device and method may capture an image of an environment, followed by identification of blocks of connected components in the image. A test for overlap of spans may be made, between a span of a block selected (e.g. for having a line of pixels) and another span of an adjacent block located above, or below, or to the left, or to the right of the selected block and when satisfied, these two blocks are merged. Blocks may additionally be tested, e.g., for relative heights of the two blocks, and/or aspect ratio of either or both blocks, etc. Classification of a merged block as text or non-text may use attributes of the merged block, such as location of a horizontal pixel line, number of vertical pixel lines, and number of black-white transitions and number of white-black transitions in a subset of rows located below the horizontal pixel line.

Abstract: When communications of a single radio access technology (RAT), or different radio access technologies in a proximate communication spectrum are operating at the same time, potential interference between devices may occur. To reduce the interference, the time division duplex (TDD) configuration of one or more conflicting device may be altered. For example, at the edge of a communication region, TDD configurations used by edge base stations to communicate with mobile devices may be set to reduce interference. As another example, communications of a first device may be altered so the first device schedules uplink communications when a second device also has uplink communications scheduled. Other configurations may also be implemented.

Abstract translation: 当单个无线电接入技术（RAT）或邻近通信频谱中的不同无线电接入技术的通信同时工作时，可能发生设备之间的潜在干扰。 为了减少干扰，可以改变一个或多个冲突设备的时分双工（TDD）配置。 例如，在通信区域的边缘，可以设置边缘基站用于与移动设备通信的TDD配置，以减少干扰。 作为另一示例，可以改变第一设备的通信，使得当第二设备还具有调度的上行链路通信时，第一设备调度上行链路通信。 也可以实现其他配置。

Abstract: Techniques to enhance the performance in a wireless communication system using segments called subbands and using precoding are shown. According to one aspect, the bandwidth for transmission to an access terminal is constrained to a preferred bandwidth which is less than the bandwidth available for transmission to an access terminal and precoding information related to the subcarriers within the constrained bandwidth is provided to a transmitter. The precoding information related to the subcarriers within a constrained bandwidth provides feedback about the forward link channel properties relative to different subbands and may be fed back on a channel associated with the bandwidth.

Abstract: An electronic device and method use a camera to capture an image of an environment outside the electronic device followed by identification of regions, based on pixel intensities in the image. At least one processor automatically computes multiple values of an indicator of skew in multiple regions in the image respectively. The multiple values are specific to the multiple regions, and thereafter used to determine whether unacceptable skew is present across the regions, e.g. globally in the image as a whole. When skew is determined to be unacceptable, user input is requested to correct the skew, e.g. by displaying on a screen, a symbol and receiving user input (e.g. by rotating an area of touch or rotating the electronic device) to align a direction of the symbol with a direction of the image, and then the process may repeat (e.g. capture image, detect skew, and if necessary request user input).
