摘要： Methods and devices for coding of feature locations are disclosed. In one embodiment, a method of coding feature location information of an image includes generating a hexagonal grid, where the hexagonal grid includes a plurality of hexagonal cells, quantizing feature locations of an image using the hexagonal grid, generating a histogram to record occurrences of feature locations in each hexagonal cell, and encoding the histogram in accordance with the occurrences of feature locations in each hexagonal cell. The method of encoding the histogram includes applying context information of neighboring hexagonal cells to encode information of a subsequent hexagonal cell to be encoded in the histogram, where the context information includes context information from first order neighbors and context information from second order neighbors of the subsequent hexagonal cell to be encoded.

摘要： A method for feature matching in image recognition is provided. First, image scaling may be based on a feature distribution across scale spaces for an image to estimate image size/resolution, where peak(s) in the keypoint distribution at different scales is used to track a dominant image scale and roughly track object sizes. Second, instead of using all detected features in an image for feature matching, keypoints may be pruned based on cluster density and/or the scale level in which the keypoints are detected. Keypoints falling within high-density clusters may be preferred over features falling within lower density clusters for purposes of feature matching. Third, inlier-to-outlier keypoint ratios are increased by spatially constraining keypoints into clusters in order to reduce or avoid geometric consistency checking for the image.
摘要翻译：提供了一种图像识别中的特征匹配方法。首先，图像缩放可以基于用于图像的尺度空间上的特征分布来估计图像尺寸/分辨率，其中使用不同尺度的关键点分布中的峰值来跟踪主要图像尺度并粗略地跟踪对象尺寸。第二，不是使用图像中的所有检测到的特征来进行特征匹配，而是可以基于簇密度和/或检测关键点的比例级别来修剪关键点。落入高密度簇内的关键点可能优于落入低密度簇内的特征，用于特征匹配。第三，通过空间约束关键点进入群集来增加从早到晚的关键点比例，以便减少或避免图像的几何一致性检查。

摘要： This disclosure describes the use of non-dyadic discrete cosine transform (DCT) sizes for performing a DCT. Similarly, this disclosure describes the use of non-dyadic inverse discrete cosine transform (IDCT) sizes for performing an IDCT. Using non-dyadic transform sizes may be less computationally expensive compared to using conventional dyadic transform sizes. Aspects of this disclosure may be useful in any device or system that performs a DCT or IDCT.

摘要： A multiple access technique for a wireless communication system establishes separate channels by defining different time intervals for different channels. In a transmitted reference system different delay periods may be defined between transmitted reference pulses and associated data pulses for different channels. In addition, a multiple access technique may employ a common reference pulse for multiple channels in a transmitted reference system. Another multiple access technique assigns different pulse repetition periods to different channels. One or more of these techniques may be employed in an ultra-wide band system.

摘要： A signaling scheme employs transmitted reference pulses having varying phase. The phase of the reference pulses may be varied in a random manner or in accordance with a data stream. In some aspects a transmitter modulates the phase of the reference pulses to encode an additional data stream in a transmitted reference signal. In some aspects these techniques are employed in a heterogeneous network including coherent and non-coherent receivers. In some aspects these techniques may be employed in an ultra-wide band system.

摘要： For position determination with peer-to-peer communication, a target terminal broadcasts a request for assistance in determining its position. At least one ranging terminal receives the request. Each ranging terminal sends a response with a time of arrival (TOA) measurement for the request and the position of the ranging terminal. For two-way peer-to-peer, the target terminal receives at least one response from the at least one ranging terminal, obtains a TOA measurement for each response, estimates the distance to each ranging terminal based on the TOA measurement for the request and/or the TOA measurement for the response, and computes a position estimate for itself based on the estimated distance and the position for each ranging terminal. For one-way peer-to-peer, a network entity receives at least one response from the at least one ranging terminal, computes a position estimate for the target terminal, and sends the position estimate to the target terminal.
