(Object) To provide an information processing system capable of presenting important information immediately. (Means of Achieving the Object) An information processing system according to the present disclosure includes a terminal device and an information processing apparatus configured to receive content data from the terminal device. The information processing system includes: a reference storage unit storing reference information indicating an important item; an important item extracting unit configured to extract important item information indicated by the reference information from the content data, by referring to the reference storage unit; an important item storing unit configured to store the extracted important item information into an important item storage unit; and a display control unit configured to display the important item information stored in the important item storage unit on a display device of the terminal device, in response to receiving a display request of the important item information.

Embodiments of the present invention disclose a method, computer program product, and system for an interactive image file. The computer may receive at least one image and a plurality of business logic associated with the at least one image. The at least one image may be encoded into at least one image block, wherein the at least one image block contains a plurality of images stored within a single file at different offsets. A table of contents may be generated for the at least one image block, wherein the table of contents contains a list of the at least one image block, a location of the at least one image block, and an identifier for each of the at least one image block. A single image file may be created for the interactive image file.

Embodiments of the present disclosure disclose a method and an apparatus for operating a control system, a storage medium, and an electronic apparatus. The method includes: obtaining, by using a target recording device in a control system, first image information of a target object moving in a real scene; obtaining a first distance corresponding to the first image information, the first distance being a distance between the target recording device and the target object; and adjusting a target parameter of the control system according to the first distance, the target parameter being used for outputting media information to a virtual reality (VR) device, the VR device being connected to the control system, the media information being corresponding to movement information of the target object moving in the real scene, and the movement information comprising the first distance.

An apparatus configured for head-worn by a user, includes: a screen configured to present graphics for the user; a camera system configured to view an environment in which the user is located; and a processing unit coupled to the camera system, the processing unit configured to: obtain a first image with a first resolution, the first image having a first corner, determine a second image with a second resolution, the second image having a second corner that corresponds with the first corner in the first image, wherein the second image is based on the first image, the second resolution being less than the first resolution, detect the second corner in the second image, determine a position of the second corner in the second image, and determine a position of the first corner in the first image based at least in part on the determined position of the second corner in the second image.

Embodiments of the present disclosure disclose a method, apparatus, server and storage medium for image retrieval. The method includes: identifying a plurality of groups of images having identical contents from images on all webpages; aggregating, for each image group, image-related texts on all source webpages of each image to obtain text descriptions of each image group; establishing an inverted index for each image in the image groups based on the text descriptions of the image group, the inverted index at least including, for each text description, source webpages corresponding to all text descriptions of the image group of the text description; and performing image retrieval based on an inputted query and the inverted index.

Systems and methods are disclosed for controlling image annotation. One method includes acquiring a digital representation of image data and generating a set of image annotations for the digital representation of the image data. The method also may include determining an association between members of the set of image annotations and generating one or more groups of members based on the association. A representative annotation from the one or more groups may also be determined, presented for selection, and the selection may be recorded in memory.

Aspects of the disclosure relate to validating map data using challenge questions. For instance, an attributes to be validated may be identified from the map data. At least one challenge question may be selected from a plurality of predetermined challenge questions based on the attribute. An image may be retrieved based on image information associated with the at least one challenge question. The image and the at least one challenge question may be provided for display. In response to the providing, operator input identifying an answer to the at least one challenge question may be received. This answer may be then used to validate the attribute.

A system for archival and access of image content is provided. The system includes a database configured to store one or more interactive images collected from a social media platform. The system further includes an archival subsystem coupled to the database. The archival subsystem is configured to receive the one or more interactive images from the database. The archival subsystem is also configured to archive the one or more interactive images based on a plurality of parameters, where the plurality of parameters includes a location and a contributor. The system further includes an access subsystem coupled to the archival subsystem. The access subsystem is configured to provide an access of one or more archived interactive images based one or more features, where the one or more feature includes proximity, permission or popularity.

Method of retrieving event information is presented. Memento objects can be recognized by an archive engine. Based on the recognition, the archive engine obtains information related to the memento object, possibly one or more recognizable features, and uses the information to search for events associated with a timeline that have corresponding tags. The archive engine can then return the event information as a result set to a user.

A computer-implemented method of associating digital tags with digital files comprises storing a plurality of digital files having embedded therein content data and metadata including tags; receiving, via a user interface device of a client device, a first tag label containing alphanumeric text created and inputted by a user of the client device; modifying, using a controller device, a selected first one of the tags of the metadata in a first of the digital files to include the first tag label; receiving, via the user interface device or another user interface device, an instruction to search for all of the digital files having at least the first tag label; responsive to receiving the instruction, automatically searching for all of the digital files having at least the first tag label; and displaying, on a video display device associated with the client device, a first indication of the first tag label.
