Abstract: Objects can be rendered in three-dimensions and viewed and manipulated in an augmented reality environment. Background images are subtracted from object images from multiple viewpoints to provide baseline representations of the object. Morphological operations can be used to remove errors caused by misalignment of an object image and background image. Using two different contrast thresholds, pixels can be identified that can be said at two different confidence levels to be object pixels. An edge detection algorithm can be used to determine object contours. Low confidence pixels can be associated with the object if they can be connected to high confidence pixels without crossing an object contour. Segmentation masks can be created from high confidence pixels and properly associated low confidence pixels. Segmentation masks can be used to create a three-dimensional representation of the object.

Abstract: Video footage captured by A/V recording and communication devices may be readily uploaded to the cloud and shared with a requesting party, such as a law enforcement agency. When a request is received from a requesting party for video footage, videos meeting the criteria specified by the requesting party may be determined. Consent requests may then be sent to users associated with each of the A/V recording and communication devices that recorded the videos meeting the criteria specified by the requesting party. When user consents to share the videos, the videos may be provided to the requesting party.

Abstract: Parcel theft deterrence for audio/video (A/V) recording and communication devices, such as video doorbells and security cameras. When an A/V recording and communication device captures image data that includes a parcel, a parcel boundary may be created for monitoring the parcel within. In various embodiments, when the parcel is removed from the parcel boundary, a user alert may be generated to notify a user of a client device associated with the A/V recording and communication device that the parcel has been removed.

Abstract: An object recognition system can be adapted to recognize subject matter having very few features or limited or no texture. A feature-sparse or texture-limited object can be recognized by complementing local features and/or texture features with color, region-based, shape-based, three-dimensional (3D), global, and/or composite features. Machine learning algorithms can be used to classify such objects, and image matching and verification can be adapted to the classification. Further, multiple modes of input can be integrated at various stages of the object recognition processing pipeline. These multi-modal inputs can include user feedback, additional images representing different perspectives of the object or specific regions of the object including a logo or text corresponding to the object, user behavior data, location, among others.

Abstract: Approaches provide for an interactive interface for determining annotation information that can be used to recommend content, improve user interaction and satisfaction, as well as improve various image recognition approaches. For example, a user can be presented an interactive interface, such as a game. The interactive interface can include colored graphical elements, where each graphical element can be associated with and display a visual feature of an item. A user can be provided a task or goal, such as to select, move, or otherwise arrange graphical elements based on a visual feature of the elements. The user interaction can generate annotation information that can be utilized to determine related content as well as improve various image recognition approaches.

Abstract: A security network provides reduced power consumption and more robust communication of messages in comparison to conventional wireless systems. Reducing power consumption as discussed herein ensures that the security system is able to operate for a long duration of time, potentially with minimal or no power from an electrical grid. Additionally, redundant communication paths as discussed herein provide a more robust way of selectively forwarding security data to a remote server. The availability of multiple communication paths ensures that a respective remote target recipient such as a server resource or remote communication device operated by a user can be notified of a trigger event during power failure conditions, such as when certain communication functionality of a security system is disabled.

Abstract: Approaches provide for updating information associated with points and/or objects of interest, such as businesses and other such entities. For example, an update service can analyze image data to determine visual features of a visual representation of a business. The visual features can be compared to information stored in a database. The information stored in the database can be derived from previously obtained image data that includes visual features corresponding to the business. A change in the visual representation of the business can be determined. The change might be due to, for example, a change in the business operating at that location which can result in a change in the visual appearance of the business; an update to business hours, contact information, or other information. Once the change is determined to at least a threshold amount, an event to update business information (e.g., the name of the business, contact information, images, etc.

Abstract: A method for network configuration sharing includes receiving a home network configuration associated with a user, identifying an away network, and modifying the configuration of the away network based on the configuration of the home network.

Abstract: In embodiments of the present invention improved capabilities are described for providing intelligent power control in response to an external power interruption, causing a processor is in an electrical fixture to interrogate an external power control switch to gain an understanding of the switch's state, where prior to the external power interruption the electrical fixture may be powered by external power and where external power may be connected and disconnected by a user of the switch. In the event that the switch's state is determined to be such that it would normally pass power to the electrical fixture, the processor causes the electrical fixture to operate using a backup power supply. In the event that the switch's state is determined to be such that it would normally not pass power to the electrical fixture, the processor causes the electrical fixture to act as if the user of the switch has intentionally removed power.

Abstract: Objects can be rendered in three dimensions and viewed and manipulated in an augmented reality environment. A number of object images, a number of segmentation masks, and an object mesh structure are used by a client device to render the object in three dimensions. The object images and segmentation masks can be sequenced into frames. The object images and segmentation masks can be partitioned into patches and sequenced, or ordered, within each patch, and a keyframe can be assigned in each patch. Then, the object images and segmentation masks can be encoded into video files and sent to a client device. The client device can quickly retrieve a requested object image and segmentation mask based at least in part on identifying the keyframe in the same patch as the object image and segmentation mask.

Abstract: Various embodiments provide for the generation of 3D models of objects. For example, depth data and color image data can be captured from viewpoints around an object using a sensor. A camera having a higher resolution can simultaneously capture image data of the object. Features between images captured by the image sensor and the camera can be extracted and compared to determine a mapping between the camera and the image. Once the mapping between the camera and the image sensor is determined, a second mapping between adjacent viewpoints can be determined for each image around the object. In this example, each viewpoint overlaps with an adjacent viewpoint and features extracted from two overlapping viewpoints are matched to determine their relative alignment. Accordingly, a 3D point cloud can be generated and the images captured by the camera can be projected on the surface of the 3D point cloud to generate the 3D model.
