  • Publication number: 20140105489
    Abstract: A system and method, which may be an offline method, extracts relevant image features about images in a network-based publication system for enabling image similarity searching of such images. An image is uploaded and may be sent to a picture processing service, which generates 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 images by image similarity at scale. A similar process can be performed for an image query for searching the search database for images similar to the query image.

  • Publication number: 20120210769
    Abstract: An apparatus and method for supporting a contamination detection system for determining the presence and levels of foreign particles and/or water in fluid samples, such as fuel. The apparatus may include a contamination detection system, a hollow rod, and a bypass tube. The contamination detection system may have a flush mode in which the fluid bypasses a detection monitor of the contamination detection system, flowing into the hollow rod. The contamination detection system may also have a test mode in which the fluid passes through the detection monitor, through the bypass tube and then into the hollow rod. The hollow rod may be mounted to a collection container for receiving fluid from the hollow rod. A ground wire for eliminating static build up during contamination testing may be conductively coupled with the hollow rod and may be supported on a ground wire support structure fixed to the collection container.

  • Publication number: 20110314031
    Abstract: A weighted combination of attributes including but not limited to color, shape, pattern, brand, style, size, and material may be used to rank items when searching for similar items of a given category on an ecommerce system website. The weights on each attribute may be optimized by using feedback from users, the feedback indicating the importance of each attribute to a purchaser when searching for similar items of various categories. Alternatively, click-through patterns from the ecommerce system website can be mined and used to optimize the importance of each attribute to users by item category. The optimum attribute weights for that items category are used to rank the results in a search for similar items in that category.

  • Publication number: 20110235902
    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.

  • Publication number: 20110238659
    Abstract: Using a processor, receiving, a query including a query image. A database is searched for a set of images similar to the query image, using a two-pass search. The results of the searching are then provided, the results including image members of the set of images similar to the query image. The first pass may be performed using a TF-IDF algorithm and the second pass ranks a predetermined number of results from the first pass by a best match algorithm or other type of algorithm. The type of second pass algorithm may be selectable by a user. If an end signal is not detected, a further two-pass search may be made based on a subsequent query having a subsequent query image. The subsequent query image may one of the results of the previous two pass search. A subsequent query image may change from an image of a product of a first product category to an image of a product of a second product category.
