In the past, databases containing three dimensional images were searched by keywords and indexes. For such functionality, a set of keywords must be associated with each image. This is usually performed by a person and is prone to errors. It has now been found that searching of three-dimensional images stored electronically can be performed in dependence upon a variety of criteria such as colour, shape, size, etc. A method is disclosed for searching three dimensional images of objects in dependence upon the above criteria, other images, or other criteria. This obviates the need for keyword indexing of image databases.

A method and system for visually annotating an image. Annotations and notes to images, such as digital medical and healthcare images, may be stored in a structured vector representation alongside image information in a single, non-volatile and portable file or in a separate file from the image. The annotations may be composed of point, line and polygon drawings and text symbols, labels or definitions and captions or descriptions. The annotations may be structured in a manner that facilitates grouping and manipulation as user defined groups. The annotations may be related to an image but not inextricably bound such that the original image is completely preserved. Annotations may further be selectively displayed on the image for context appropriate viewing. The annotations may be retrieved for purposes such as editing, printing, display, indexing and reporting for example, and may be displayed on an image for interactive use with an embedded self-contained user interface.

In an exemplary embodiment, a method, conducted on a server, sends renderable graphics information to a client device, said graphics information including at least one set of graphics information visible from a second view region and not visible from a first view region. The method includes determining a likelihood that a viewpoint undergoes movement from said first view region to said second view region. The method further includes sending said at least one set of graphics information upon determination that the likelihood that the viewpoint undergoes movement from said first view region to said second view region is greater than a predetermined threshold, said movement determined according to a predetermined motion path.

In one example, an apparatus and method are provided for rendering map images. In one example, an apparatus (e.g., a map server) includes logic for causing the transfer of tiled vector image data in response to a map request, wherein the vector data is associated with stored map data divided into a plurality of tiles. The tiled vector image data is transferred to a remote device (e.g., a client device) for rendering of the map image. Additionally, the vector image data may comprise one or more attributes associated therewith, the one or more attributes configurable by a receiving device. For example, the map image may be rendered (e.g., customized) based on one or more local attributes to vary the language used, colors, how items in the map are displayed, and other imaging characteristics of the map image.

System and method for performing Collaborative Filtering while preserving complete user anonymity are provided. Each of a group of client devices sends a rating vector anonymously to a server. The cells in each rating vector correspond to a set of items, and selected cells have ratings provided by the user associated with the corresponding client device for the corresponding items. The server aggregates all the rating vectors into a rating matrix, and factorizes the rating matrix into a user feature matrix and an item feature matrix through approximation, such that the rating matrix equals the product of the user feature matrix and the item feature matrix. The item feature matrix is sent to the client devices. Each of the client devices calculates its own user feature vector based on its rating vector and the item feature matrix, and provides personalized recommendations on selected items based on the client's user feature vector and the item feature matrix.

Various aspects of the subject technology relate to systems, methods, and machine-readable media for composition aware image querying. A system may receive user input identifying a search query for content from a client device, where the user input indicates one or more queries assigned to one or more regions of a search input page. The system may generate a query vector for each query using a computer-operated neural language model. The system may compare the query vector to an indexed vector for each region of an image. The system may determine a listing of composition-specific images from a collection of images based on the comparison. The system may determine a ranking for each image in the listing of composition-specific images, and provide search results responsive to the search query to the client device. The search results may include a prioritized listing of the composition-specific images based on the determined ranking.

The invention relates to a method and a system for fast making a vector font library. The system comprises a computer, a printer and a scanner. The method includes the steps of firstly, appointing character contents of a to-be-built font library and writing the same in a standard form through a machine; secondly, writing characters according to writing standards in the printed standard form through handwriting, and using the standard form as unit to collect the handwriting characters to obtain a plurality of form images; thirdly, segmenting the form images to obtain character closed contours, selecting some points as key points according to the character closed contours, and screening the key points to obtain optimal key point; fourthly, obtaining character vector contours according to the optimal key point, and generating the standard TrueType font library according to the character vector contours. The vector font library made by the method is high in quality, writing style of an original writer can be kept completely, no manual intervention is needed during font library generating, the high-quality standard font library is generated at one step by the scanned images, and batch production of personalized font libraries is facilitated.

The invention provides an information recommendation method. The method comprises the steps of obtaining image information, and according to the image information, generating a user tag set corresponding to user identifiers, wherein the image information has the corresponding user identifiers; according to user tags in the user tag set and the corresponding image information, forming eigenvectorscorresponding to the user identifiers; inputting the eigenvectors to a trained information recommendation model, and outputting recommendation parameters of users for to-be-recommended information; and according to the recommendation parameters, recommending the to-be-recommended information to terminals corresponding to the user identifiers. The user tag set capable of reflecting user features isestablished through the image information; the recommendation parameters of the users for the recommended information are predicted by adopting the trained information recommendation model accordingto the user tag set; and the recommendation is performed according to the recommendation parameters, so that the recommendation accuracy is improved and the users not interested in the information areprevented from being disturbed. In addition, the invention provides an information recommendation apparatus, a computer device and a storage medium.
