    • A method is disclosed for finding a deformed pattern in an image using a plurality of sub-patterns. By advantageously restricting sub-pattern search ranges, search speed is improved, and the incidence of spurious matches is reduced. The method also quickly decides which sub-pattern result, of several potential candidates, is most likely to be the correct match for a deformed sub-pattern. Also, a method is provided for characterizing a deformed pattern in an image by using results from feature-based search tools to create a mapping that models the deformation of the pattern. A transform, selectable by a user, is fit to the results from the search tools to create a global deformation mapping. This transformation is fit only to feature points derived from matches resulting from successful sub-pattern search, without including data from areas of the pattern that were blank, not matched, or otherwise didn't contain information about the pattern's distorted location.
    • 公开了一种使用多个子图案在图像中发现变形图案的方法。 通过有利地限制子图案搜索范围,提高了搜索速度,并且减少了错配匹配的发生。 该方法还快速地确定几个潜在候选者的哪个子模式结果最有可能是变形子模式的正确匹配。 此外,提供了一种通过使用基于特征的搜索工具的结果来表征图像中的变形图案以创建对图案的变形进行建模的映射的方法。 由用户选择的变换适用于搜索工具的结果,以创建全局变形映射。 该变换仅适合于从成功的子模式搜索产生的匹配导出的特征点,而不包括来自空白,不匹配的模式的区域的数据,或者否则不包含关于模式的失真位置的信息。

    • A method, computer program product, and computer system for receiving a video at a computer device. The video includes a plurality of time codes corresponding to a plurality of video segments of the video. At least a portion of the plurality of video segments is played via a user interface operating on the computer device. A comment corresponding to a first video segment of the plurality of video segments is received via the user interface. The comment is associated with a first time code of the plurality of time codes, where the first time code corresponds to the first video segment. The comment is synchronized with playback of the video.

    • A method is provided for dividing a pattern into a plurality of sub-patterns, each sub-pattern being adapted for use with an image search method that can provide a plurality of sub-pattern search results. The method represents the pattern as a plurality of feature points, generates candidate partitions of the plurality of feature points, and then scores the candidate partitions by examining characteristics of each potential sub-pattern of each candidate partition. The highest-scoring partition is selected, and then it is applied to the plurality of feature points, creating one or more sub-pluralities of features. The invention advantageously provides a plurality of sub-patterns where each sub-pattern contains enough information to be located with a feature-based search method, where that information has been pre-evaluated as being useful and particularly adapted for running feature-based searches.
    • 提供了一种用于将图案划分成多个子图案的方法,每个子图案适于与能够提供多个子图案搜索结果的图像搜索方法一起使用。 该方法表示作为多个特征点的图案,生成多个特征点的候选分区,然后通过检查每个候选分区的每个潜在子模式的特征来对候选分区进行分数。 选择最高分数分区,然后将其应用于多个特征点,创建一个或多个子多个特征。 本发明有利地提供了多个子模式,其中每个子模式包含足够的信息以使用基于特征的搜索方法来定位,其中该信息已被预先评估为有用的并且特别适用于运行基于特征的搜索。

    • An actuator for selectively causing axial compression of friction elements in a clutch is disclosed. The actuator comprises a pair of beveled wedge washers and a bearing race supported between the washers. The race supports conical bearing rollers in a generally radial orientation. An actuator plate is mounted for rotation relative to the bearing race and includes bearing ramp surfaces that are operable to move the conical bearing rollers radially inwardly thereby forcing the washers to move apart axially and to thereby cause compression of and torque transfer through the friction elements. A clutch including the actuator is well suited for inclusion in a transfer case.
    • 公开了一种用于选择性地引起摩擦元件在离合器中的轴向压缩的致动器。 致动器包括一对斜楔形垫圈和支撑在垫圈之间的轴承座。 赛道以大致径向方向支撑圆锥滚子轴承。 致动器板被安装成相对于轴承座旋转,并且包括可操作以径向向内移动锥形轴承辊的轴承斜面,从而迫使垫圈轴向移动,从而引起通过摩擦元件的压力和扭矩传递。 包括致动器的离合器非常适合包含在转运箱中。
