摘要： Local features of retrieved images are identified and for each image, an ordered bag-of-features is created that describes the features of the image. Spatial relationships between features of an image are captured in histogram descriptors created from linear or circular projections. Using the histogram descriptors, ordered bags-of-features describing the features of the images are developed. Calibrating the ordered bags-of-features to account for spatial variance leads to spatial bags-of-features.
摘要翻译：识别检索到的图像的本地特征，并且对于每个图像，创建描述图像的特征的有序的特征袋。图像特征之间的空间关系被捕获在从线性或圆形投影创建的直方图描述符中。使用直方图描述符，开发了描述图像特征的有序的特征袋。校准订购的特征袋以考虑空间差异导致空间特征袋。

摘要： Sketch-based image search may include receiving a query curve as a sketch query input and identifying a first plurality of oriented points based on the query curve. The first plurality of oriented points may be used to locate at least one image having a curve that includes a second plurality of oriented points that match at least some of the first plurality of oriented points Implementations also include indexing a plurality of images by identifying at least one curve in each image and generating an index comprising a plurality of oriented points as index entries. The index entries are associated with the plurality of images based on corresponding oriented points in the identified curves in the images.
摘要翻译：基于草图的图像搜索可以包括接收查询曲线作为草图查询输入，并且基于查询曲线来识别第一多个定向点。可以使用第一多个定向点来定位具有曲线的至少一个图像，该曲线包括与第一多个定向点中的至少一些匹配的第二多个定向点。实现还包括通过至少识别多个图像来索引多个图像每个图像中的一个曲线并且生成包括多个定向点作为索引条目的索引。索引条目基于图像中所识别的曲线中的对应的定向点与多个图像相关联。

摘要： Described herein is a technology that facilitates efficient automated mining of topic-related aspects of user generated content based on automated analysis of the user generated content. Locations are automatically learned based on dividing documents into document segments, and decomposing the segments into local topics and global topics. Techniques described herein include, for example, computer annotating travelogues with learned tags, performing topic learning to obtain an interest model, and performing location matching based on the interest model.

摘要： Sketch and tagging based image search may include receiving a sketch query input and identifying an object in a desired image. The object or objects of the sketch query may be tagged with a text, and searching performed based on the objects. Certain implementations include indexing patches of the images, where the patches represent the objects. Relevant images can be returned based on the index of the patches.
