Abstract: The present disclosure is directed toward systems and methods that enable more accurate digital object classification. In particular, disclosed systems and methods address inaccuracies in digital object classification introduced by variations in classification scores. Specifically, in one or more embodiments, disclosed systems and methods generate probability functions utilizing digital test objects and transform classifications scores into normalized classification scores utilizing probability functions. Disclosed systems and methods utilize normalized classification scores to more accurately classify and identify digital objects in a variety of applications.

Abstract: Systems and methods are provided for creating shared virtual spaces (“rooms”). A room may be created when a user first shares images with another user. A user may send a request to a content management system to share one or more images with various contacts. In response, a room is created by the content management system in which a copy of each image is stored. Images added to a room are copied to a separate “rooms” database, and “locked,” being saved in the room for a period of time, which may be indefinitely. Changes made by the user to a room via a user device may be displayed as soon as indicated, without waiting for the information to be sent to a system server or its state to be made consistent with that of the user device. Room activity notifications may be sent to members in various ways.

Abstract: Embodiments of the present invention analyze and score each image associated with a group to determine representative image or images for the group. Such analysis can include detecting objects shown in the images, determining the quality of the images, and/or contextually analyzing the images as a group. In some embodiments, each image in a group (e.g., an event) of images can be analyzed by one or more image analysis modules that calculate a score for the image based on a different image characteristic. A composite image score can then be calculated based on the various image characteristic scores to identify the image or images to be used as to represent the group.

Abstract: Embodiments are provided for ephemeral eventing. Ephemeral eventing may involve sending metadata portions associated with content items from a user device to a content management system prior to uploading the content portions of the content items. The content management system may then assign the content items to one or more events. The event assignments may then be sent back to the user device, allowing the content items to be locally displayed according to their events as if the content items had already been uploaded to the content management system.

Abstract: The present disclosure is directed toward systems and methods to quickly and accurately identify boundaries of a displayed document in a live camera image feed, and provide a document boundary indicator within the live camera image feed. For example, systems and methods described herein utilize different display document detection processes in parallel to generate and provide a document boundary indicator that accurately corresponds with a displayed document within a live camera image feed. Thus, a user of the mobile computing device can easily see whether the document identification system has correctly identified the displayed document within the camera viewfinder feed.

Abstract: The present disclosure is directed toward systems and methods that efficiently and effectively generate an enhanced document image of a displayed document in an image frame captured from a live image feed. For example, systems and methods described herein apply a document enhancement process to a displayed document in an image frame that result in an enhanced document image that is cropped, rectified, un-shadowed, and with dark text against a mostly white background. Additionally, systems and method described herein determine whether a stored digital content item includes a displayed document. In response to determining that a stored digital content item does include a displayed document, systems and methods described herein generate an enhanced document image of a displayed document included in the stored digital content item.

Abstract: Recommendations for shareable links to content items stored in an online content management service. In one aspect, a recommendation is sent to a first user to create and share a shareable link to a content item with a second user. The content item to share via a shareable link is identified as one that is currently not shared by the first user and that has one or more characteristics in common with a “popular” content item as determined by monitoring the popular content item for a threshold number of requests to access the popular content item via a corresponding shareable link to the popular content item.

Abstract: Systems, methods, and non-transitory computer readable media are provided for maintaining local virtual states pending server-side storage across multiple devices and users and intermittent network connections. In exemplary embodiments, content added by a user to his or her account locally on a user device may be displayed, and all interactivity therewith may be facilitated, as if the content had already been created on the content management system. In content management system applications that support shared virtual spaces, changes made by the user from his or her user device to the shared virtual space (including creation of a new shared virtual space) may be displayed locally as soon as the change has been made, not waiting for the information to be transmitted to the server or its state to be made consistent with that of the mobile device.
