    Abstract: A method and system to index and search item listings in a network-based publication system, such as a network-based marketplace. For example, a listing query may be received from a user, the listing query including a query image. The query image may then be processed to generate a plurality of index sets. Each index set of the plurality of index sets may correspond to a respective portion of the query image and may comprise a set of index values. Each index value of the set of index values may be indicative of an image attribute, such as light intensity, for a respective sub-portion of the corresponding portion of the query image. At least one result image from a database of listing images may be identified by comparing the plurality of index sets for the query image to pre-compiled index sets in an index database. Each pre-compiled index set may be associated with at least one listing image which, in turn, may be associated with an item listing on a network-based marketplace.

    Abstract translation: 一种在基于网络的发布系统（例如基于网络的市场）中索引和搜索项目列表的方法和系统。 例如，可以从用户接收列表查询，列表查询包括查询图像。 然后可以处理查询图像以生成多个索引集。 多个索引集合的每个索引组可以对应于查询图像的相应部分，并且可以包括一组索引值。 索引值集合的每个索引值可以指示针对查询图像的对应部分的相应子部分的图像属性（诸如光强度）。 来自列表图像的数据库的至少一个结果图像可以通过将查询图像的多个索引集合与索引数据库中的预编译索引集进行比较来识别。 每个预先编译的索引集合可以与至少一个列表图像相关联，其又可以与基于网络的市场上的项目列表相关联。

    Abstract: A first database search is performed for images similar to a first query image, and a first plurality of images that result from the first database search are provided. The first plurality of images are selectable to provide a second query image. A second database search is performed for images similar to the second query image, and a second plurality of images that result from the second search are provided. The second plurality of images are selectable to provide a third query image. A third database search is performed for images similar to the third query image; and a third plurality of images that result from the third database search are provided. The third plurality of images are selectable for providing a fourth query image. The search can continue to additional depths. Similarity may be determined by pixel color gradients using windows of computation.

    Abstract translation: 对与第一查询图像类似的图像执行第一数据库搜索，并且提供由第一数据库搜索产生的第一多个图像。 可选择第一多个图像以提供第二查询图像。 对与第二查询图像类似的图像执行第二数据库搜索，并且提供由第二搜索产生的第二多个图像。 可选择第二多个图像以提供第三查询图像。 对与第三查询图像类似的图像执行第三数据库搜索; 并且提供由第三数据库搜索产生的第三多个图像。 可选择第三多个图像以提供第四查询图像。 搜索可以继续增加深度。 相似度可以通过使用计算窗口的像素颜色梯度来确定。

    Abstract: A metadata extraction machine accesses an image that depicts an item. The item depicted in the image may have an attribute that describes a characteristic of the item and an attribute descriptor that corresponds to the attribute of the item and specifies a value of the attribute. The metadata extraction machine performs an analysis of the image. The analysis may include identifying the attribute descriptor corresponding to the attribute based on image segmentation of the image. The metadata extraction machine transmits a communication to a device of a user based on the identifying of the attribute descriptor corresponding to the attribute of the item depicted in the image.

    Abstract: A system and method, which may be an offline method, extracts relevant image features about listing items in a network-based publication system for enabling image similarity searching of such listing items. When a seller lists an item, an image of the item is uploaded and may be sent to a picture processing service, which generates several digests. The digests are compressed data structures each representing a particular image feature such as edge, color, texture, or words. These digests are then stored in a search database, where the digests can be used to retrieve listings by image similarity at scale. A similar process can be performed for a query listing for searching the search database for items similar to the query listing.
