摘要： One embodiment of the present invention provides a system that enhances sharpness of object boundaries in an image. During operation, the system first receives an image. Next, the system computes gradients of color values for pixels in the image. The system then computes displacement vectors for pixels in the image, wherein the magnitude of the displacement vector for a given pixel is proportional to the magnitude of the gradient of the color value at the given pixel. The system next replaces the color values for the pixels, wherein the color value for a given pixel is replaced with a color value obtained from a location at the end of the displacement vector for the given pixel.

摘要： A determination of whether a mapped business listing that is produced as a search result corresponds to an actual location of operation is based on different factors. One factor identifies whether the business listing is associated with a business category that appears as search results for a particular geographic area in numbers that exceed average proportions for the same business category density in similarly situated geographic areas. Another factor determines whether different business listings in the same geographic area include the same identifying data. Specific characteristics of a neighborhood where the business listing is mapped provide an additional factor for identifying whether a search result for a business listing is map spam. The different factors may be considered together to determine the likelihood that a mapped search result is spam.
摘要翻译：确定作为搜索结果生成的映射业务列表是否与实际操作位置相对应是基于不同的因素。一个因素是确定业务列表是否与业务类别相关联，该业务类别作为特定地理区域的搜索结果显示，该业务类别的数量超过了类似位置的地理区域中相同业务类别密度的平均比例。另一个因素决定了相同地理区域中的不同商家列表是否包含相同的标识数据。业务列表映射的邻域的具体特征提供了用于识别商业列表的搜索结果是否是垃圾邮件的附加因素。可以一起考虑不同的因素以确定映射的搜索结果是垃圾邮件的可能性。

摘要： A method is presented for marking high-quality digital images with a robust and invisible watermark. It requires the mark to survive and remain detectable and authenticatable through all image manipulations that in themselves do not damage the image beyond useability. These manipulations include JPEG “lossy” compression and, in the extreme, the printing and rescanning of the image. The watermark also has the property that it can detect if the essential contents of the image has changed. The first phase of the method comprises extracting a digest or number N from the image so that N only (or mostly) depends on the essential information content, such that the same number N can be obtained from a scan of a high quality print of the image, from the compressed form of the image, or in general, from the image after minor modifications (introduced inadvertently by processing, noise etc.). The second phase comprises the marking. This can be done in form of an invisible robust watermark, or in form of some visible signature or watermark.
摘要翻译：提出了一种用强大且不可见的水印标记高质量数字图像的方法。它需要标记生存，并通过所有图像操作保持可检测和可认证，这本身不会损害图像超出可用性。这些操作包括JPEG“有损”压缩，在极端情况下，打印和重新扫描图像。该水印还具有可以检测图像的基本内容是否已改变的属性。该方法的第一阶段包括从图像中提取摘要或数字N，使得仅N（或主要地）取决于基本信息内容，使得可以从扫描的高质量打印获得相同数量N 图像，从图像的压缩形式，或一般来说，从稍后修改的图像（通过处理，噪声等无意中引入）。第二阶段包括标记。这可以以不可见的鲁棒水印的形式或以一些可见的签名或水印的形式来完成。

摘要： A method of doing meaningful modifications on an image is presented. These modifications can then be used in variety of applications related to image shape manipulation and similar shape retrieval. The method extracts macrofeatures and microfeature from a given shape. Deformations are done on the macrofeatures only. These deformations are either predefined, or are taken from a deformation library, or are calculated from the shape itself, The microfeatures are then added to the deformed macrofeatures to get a deformed shape. The shape deformations then allow user's perception of shape similarity to be learned, which is reflected in the values of parameters in a parameterized shape similarity metric. The user can use one of the deformed shapes as the initial query point, instead of the shape he or she started with. The shape database compression is achieved by storing only the identification of a similar shape and value of global deformations which will generate this shape approximately, instead of storing every shape feature individually.
摘要翻译：提出了对图像进行有意义的修改的方法。然后，这些修改可用于与图像形状操纵和类似形状检索有关的各种应用。该方法从给定的形状提取宏特征和微特征。变形仅在宏观特征上进行。这些变形是预定义的，或者是从变形库中获取的，或者是根据形状本身计算的。然后将微特征加到变形的宏观特征中以得到变形的形状。形状变形然后允许用户对形状相似度的感知被学习，这反映在参数化形状相似性度量中的参数值中。用户可以使用其中一个变形的形状作为初始查询点，而不是他或她开始的形状。形状数据库压缩是通过仅存储将产生该形状的全局变形的类似形状和值的识别来实现的，而不是分别存储每个形状特征。

摘要： The present application discloses systems and methods for using probabilistic prioritization to assign human reviewers to review data stored in or indexed by an information system. Some embodiments include accessing an index of data items, where individual data items have a corresponding probability f of having a problem, a cost to review the data item, a penalty if a problem associated with the data item is not remedied, and a gain if a problem associated with the data item is remedied; identifying a subset of data items having a corresponding f that is greater than or equal to a decision threshold based on the data item's corresponding cost, penalty, and gain; and ranking at least a portion of the subset of data items based at least in part on their corresponding cost, f, and gain.
