摘要： Methods, systems, and apparatus, including computer programs encoded on computer storage media, for fast user enrollment for facial recognition using face clustering. One of the methods includes identifying, from a set of face images of faces, clusters of face images, where the clusters of face images include a particular cluster; receiving, from a device, an indication that the particular cluster includes a first subcluster of face images that depict a first person and a second subcluster of face images that depict a second person; in response to receiving the indication, determining that a number of face images in the first subcluster of face images that depict the first person does not satisfy an enrollment criteria; identifying another cluster of face images that depict the first person; and enrolling, in a facial recognition database, the first person using the other cluster of face images.

摘要： Disclosed are methods, systems, and apparatus for adjusting areas of interest for motion detection in camera scenes. A method includes obtaining a map of false motion event detections using a first area of interest; identifying an overlap area between the map of false detections and the first area of interest; determining a second area of interest that includes portions of the first area of interest and excludes at least a part of the overlap area; obtaining a map of true motion event detections using the first area of interest; determining whether true detections using the second area of interest compared to true detections using the first area of interest satisfies performance criteria; and in response to determining that true detections using the second area of interest compared to true detections using the first area of interest satisfies performance criteria, providing the second area of interest for use in detecting events.

摘要： Methods and systems, including computer-readable media, are described for monitoring presence or absence of an object at a property using local region matching. A system generates images while monitoring an area of the property and, based on the images, detects an object in a region of interest in the area. For each of the images: the system iteratively computes interest points for the object using photometric augmentation applied to the image before each iteration of computing the interest points. A digital representation of the region and the object is generated based on interest points that repeat across the images after each application of the photometric augmentation. Based on the digital representation, a set of anchor points are determined from the interest points that repeat across images. Using the set of anchor points, the system detects an absence or a continued presence of the object in the area of the property.

摘要： Methods, systems, and apparatus, including computer programs encoded on computer storage media, for reducing a likelihood that a doorbell might be used. One of the methods includes determining that a visitor arrived at a premises; determining that the visitor used a computing device at a first time; determining that a user device of a person of the premises received a message at a second time; determining that the first time and the second time both satisfy a timing criteria; and in response to determining that the first time and the second time both satisfy the timing criteria, sending, to the user device, a notification that indicates that the visitor arrived at the premises.

摘要： Methods, systems, and apparatus, including computer programs encoded on computer-storage media, for location tracking. In some implementations, a corresponding method includes obtaining images of one or more persons within a property; identifying a heartbeat for each person of the one or more persons within the images; identifying a location for each person within the images; receiving a request that indicates a heartbeat signature generated from heartbeats sensed by a device worn by a user; determining that an identified heartbeat of a person of the one or more persons matches the heartbeat signature; in response to determining that the identified heartbeat of the person of the one or more persons matches the heartbeat signature, selecting the person as the user; and in response to selecting the person as the user, providing a response to the request based on a location of the person.

摘要： Methods and systems, including computer programs encoded on a storage medium, are described for implementing item monitoring using a doorbell camera. A system generates an input video stream that has image frames corresponding to detection of activity at a property. Timing information is generated for the video stream and includes a timestamp for each image frame of the stream. Using the timing information, the system processes a pre-event image frame that precedes detection of the activity and a post-event image frame that coincides with detection of the activity. An image score is computed with respect to placement of a candidate item at the property in response to processing the pre-event and post-event image frames. The image score is used to determine that a first item was delivered to the property or that a second item was removed after being delivered to the property.

摘要： A computer-implemented method includes obtaining an image of an area of a property from an augmented reality device, identifying the area of the property based on the image obtained from the augmented reality device, determining that the area of the property corresponds to an event at the property or a configuration of a monitoring system of the property, and providing, in response to determining that the area of the property corresponds to the event or the configuration, information that represents the event or the configuration and that is configured to be displayed on the augmented reality device.

摘要： Methods, systems, and apparatus for removing precipitation from video are disclosed. A method includes generating, from a first set of images of a scene from a camera, a segmented background image model of the scene; obtaining a second set of images from the camera; identifying, in an image of the second set of images, a plurality of edges, determining that a first edge of the plurality of edges satisfies criteria for representing precipitation based at least in part on determining that the first edge (i) does not correspond to the background image model of the scene and (ii) extends into two or more contiguous segments of the scene; in response, classifying each of the contiguous segments as a precipitation segment; generating pixel data for each of the precipitation segments; and applying the pixel data to each precipitation segment in the image.

摘要： Systems and techniques are described for using thermal imaging to configure and/or augment temperature regulation operations within a property. In some implementations, a computing device obtains a thermal image of a region of a property. The thermal image identifies at least a surface within the region. A surface temperature of the surface is determined. An ambient temperature for the region is determined based at least on the surface temperature. The one or more temperature controls for the region are adjusted based at least on the ambient temperature.
