Patent number: 9928412Abstract: A large synthetic 3D human body model dataset using real-world body size distributions is created. The model dataset may follow real-world body parameter distributions. Depth sensors can be integrated into mobile devices such as tablets, cellphones, and wearable devices. Body measurements for a user are extracted from a single frontal-view depth map using joint location information. Estimates of body measurements are combined with local geometry features around joint locations to form a robust multi-dimensional feature vector. A fast nearest-neighbor search is performed using the feature vector for the user and the feature vectors for the synthetic models to identify the closest match. The retrieved model can be used in various applications such as clothes shopping, virtual reality, online gaming, and others.Type: GrantFiled: October 14, 2015Date of Patent: March 27, 2018Assignee: eBay Inc.Inventors: Qiaosong Wang, Robinson Piramuthu, Vignesh Jagadeesh, Bryan Kent Ressler

Publication number: 20180039866Abstract: An image is passed through an image identifier to identify a coarse category for the image and a bounding box for a categorized object. A mask is used to identify the portion of the image that represents the object. Given the foreground mask, the convex hull of the mask is located and an aligned rectangle of minimum area that encloses the hull is fitted. The aligned bounding box is rotated and scaled, so that the foreground object is roughly moved to a standard orientation and size (referred to as calibrated). The calibrated image is used as an input to a fine-grained categorization module, which determines the fine category within the coarse category for the input image.Type: ApplicationFiled: October 19, 2017Publication date: February 8, 2018Inventors: Mohammadhadi Kiapour, Wei Di, Vignesh Jagadeesh, Robinson Piramuthu

Publication number: 20170364536Abstract: A configured machine performs image matching and retrieval of natural images that may depict logos. The machine generates and uses color-localized spatial masks, which may be computationally less expensive than spatial verification techniques. Key points are detected within images that form a reference database of images. Local masks are defined by the machine around each key point based on the scale and orientation of the key point. To utilize color information presented in logo images, ordered color histograms may be extracted by the machine from locally masked regions of each image. A cascaded index may then be constructed for both visual descriptors and color histograms. For faster matching, the cascaded index maps the visual descriptors and color histograms to a list of relevant or similar images. This list may then be ranked to generate relevant matches for an input query image.Type: ApplicationFiled: July 3, 2017Publication date: December 21, 2017Inventors: Wei Di, Vignesh Jagadeesh, Robinson Piramuthu, Rohit Pandey, Anurag Bhardwaj

Publication number: 20160217157Abstract: Products (e.g., books) often include a significant amount of informative textual information that can be used in identifying the item. An input query image is a photo (e.g., a picture taken using a mobile phone) of a product. The photo is taken from an arbitrary angle and orientation, and includes an arbitrary background (e.g., a background with significant clutter). From the query image, the identification server retrieves the corresponding clean catalog image from a database. For example, the database may be a product database having a name of the product, image of the product, price of the product, sales history for the product, or any suitable combination thereof. The retrieval is performed by both matching the image with the images in the database and matching text retrieved from the image with the text in the database.Type: ApplicationFiled: December 17, 2015Publication date: July 28, 2016Inventors: Kevin Shih, Wei Di, Vignesh Jagadeesh, Robinson Piramuthu
