    • 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.

    • 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。

    • Per one embodiment, a method is provided for refining a pose estimate of a model. The model is coarsely aligned with a run-time image, and it represents a 2D pattern. The pose estimate includes at least one pose estimate parameter. The model has a plurality of model features, and the run-time image has a plurality of run-time features. A given distance value is determined representing a given distance between a given one of the plurality of the model features mapped by a given pose estimate and a corresponding given run-time feature. A two-dimensional model description of the two-dimensional model pattern is provided. The two-dimensional model pattern is mapped using the given pose estimate to create a transformed version of the two-dimensional model pattern. The transformed version represents a non-linear movement of at least portions of the two-dimensional model pattern in a direction orthogonal to a plane of the two-dimensional model description.

    • Computer system, method and program for making routing decisions. A best routing path according to an OSPF, IGRP, EIGRP, BGP or other routing function that can provide multiple routing paths is determined. A first multiplicity of routers in the best routing path is determined. If each of the first multiplicity of routers had a degree of availability and/or quality of signal during a predetermined prior interval that met predetermined respective thresholds, the message packet is forwarded to a next hop in the best routing path. If not, a second multiplicity of routers in a second best routing path determined according to said OSPF, IGRP, EIGRP, BGP or the other routing function is identified. If each of the second multiplicity of routers had a degree of availability and/or quality of signal during a predetermined prior interval that met respective thresholds, the message packet is forwarded to a next hop in the second best routing path.

    • A system, method and computer program for routing a response packet in a session along a path similar to a request packet's outbound path that includes a firewall and a first router. The firewall receives the request packet and forwards the request packet to the first router. Upon receipt of the request packet, the firewall and first router broadcast session information to their respective sets of directly connected devices. A second router receives the response packet. After determining that the second router was not in the outbound path according to the second router's session table, the second router forwards the response packet to the device (i.e., the firewall or the first router) that is most upstream in the outbound path among the outbound path devices that are available and connected to the second router.
