    • A system and method are provided for framing messages in a data streams encoded with redundant information for transmission and recovering the messages at a receiver. The transmission method accepts an energy waveform representing N words at a first bit rate, encoded with redundant information, where each word includes P number of bits. The N words are transformed, creating N transcoded words, where each transcoded word includes Q number of bits, and where Q 1 and each lane receives a frame of N/M transcoded words. A frame alignment marker is generated and mapped into each frame. Each frame is represented as an energy waveform that is transmitted on a corresponding physical lane at the first bit rate divided by M.
    • 提供了一种用于在用冗余信息编码的数据流中对消息进行成帧的系统和方法,用于在接收机处传输和恢复消息。 传输方法接收表示以冗余信息编码的第一比特率的N个字的能量波形,其中每个字包括P个比特数。 N个单词被变换,创建N个代码转换的单词,其中每个代码转换的单词包含Q个位数,并且其中Q 1并且每个通道接收N / M个转码字的帧。 生成帧对准标记并将其映射到每个帧中。 每帧被表示为在相应物理通道上以第一比特率除以M发送的能量波形。

    • A system and process for identifying corresponding points among multiple images of a scene is presented. This involves a multi-view matching framework based on a new class of invariant features. Features are located at Harris corners in scale-space and oriented using a blurred local gradient. This defines a similarity invariant frame in which to sample a feature descriptor. The descriptor actually formed is a bias/gain normalized patch of intensity values. Matching is achieved using a fast nearest neighbor procedure that uses indexing on low frequency Haar wavelet coefficients. A simple 6 parameter model for patch matching is employed, and the noise statistics are analyzed for correct and incorrect matches. This leads to a simple match verification procedure based on a per feature outlier distance.
    • 提出了一种用于识别场景的多个图像中的对应点的系统和过程。 这涉及到基于新类不变特征的多视图匹配框架。 特征位于哈里斯角的尺度空间,并使用模糊的局部渐变。 这定义了对特征描述符进行采样的相似度不变帧。 实际形成的描述符是强度值的偏置/增益归一化补丁。 使用在低频Haar小波系数上使用索引的快速最近邻程序来实现匹配。 采用一个简单的6参数模型进行补丁匹配,并对噪声统计进行了正确和不正确的匹配分析。 这导致基于每个特征异常距离的简单匹配验证过程。
