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.

There are provided contextual image presentation systems and methods. Such a system includes a hardware processor and a system memory having stored therein a contextual image generator including a data mapping module and a data visualization module. The contextual image generator receives social media data describing social media posts, determines a geographical location corresponding to at least some of the social media posts, and identifies a subject category corresponding respectively to each of the social media posts. In addition, the contextual image generator groups the social media posts into social media collections based on at least one of the subject category and the geographical location corresponding to each social media post. The contextual image generator further generates a contextual image that visually associates at least one of the social media collections with the subject category and/or the geographical location used to group that social media collection.

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.

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.

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.

A computer system and a fault tolerance processing method thereof of image file are provided. In the method, whether to segment the image file is determined. The image file is segmented into multiple image segmented files sequentially, and a segmenting process is recorded in response to determining to segment the image file. The segmenting process relates to a number of a last segmented file. Each time the image file is segmented once, the number of the last segmented file is accumulated. Segmenting the image file is continued according to the segmenting process in response to a segmenting exception situation. On the other hand, the deployment for the image file is performed in conjunction with a record of the current progress during the deployment, so that the deployment also can be continued in response to an interruption of the deployment. Accordingly, efficiency and successful rate can be improved.
