The methods, systems, and apparatus include actions of receiving a first video and a second video, determining first time stamps from pixels in the first video, determining second time stamps from pixels in the second video, determining an earliest frame in each of the videos that time stamps match, pairing the earliest frames, determining that a subsequent frame in each of the videos have corresponding time stamps that have a difference that satisfies a criteria, and pairing the subsequent frame in the first video with a frame after the subsequent frame in the second video.

Abstract: A method and apparatus for determining a building/urban profile image location includes extracting a building/urban profile from an obtained image and comparing the image to a database of building/urban profiles. The database may be created by obtaining point cloud data sets scanned building/urban profiles, converting the obtained point cloud data sets to a corresponding 3D surface model, and creating the database of stored building/urban profiles viewed from multiple locations within each of the 3D surface models. By comparing the extracted building/urban profile image with the stored building/urban profiles contained within the database and finding a match the location from which the extracted building/urban profile image was taken can be determined.

The methods, systems, and apparatus include actions of detecting an object near a camera, in response to detecting the object near the camera, classifying the object as a particular type of animal based on an appearance of the object in an image captured by the camera, determining whether to provide a notification regarding the image based on the particular type of animal that the object is classified as, and in response to determining to provide a notification regarding the image based on the particular type of animal that the object is classified as, providing the notification regarding the image.

Abstract: A computer-implemented method includes obtaining data from one or more non-visual sensors and a camera from a first monitoring system. The data includes non-visual data from the non-visual sensors and visual data obtained from the camera. The non-visual data from the non-visual sensors are paired with corresponding visual data from the camera. Data points of the non-visual data are synchronized with frames of the visual data based on a likelihood of an event indicated in the non-visual data. The synchronized data points of the non-visual data with the frames of the visual data are provided as labeled input to a neural network to train the neural network to detect the event. The trained neural network is provided to one or more cameras corresponding to one or more additional monitoring systems to detect the event in the visual data obtained by the one or more cameras.

Abstract: Methods, systems, and apparatus, including computer programs encoded on a storage device, for monitoring a vehicle is disclosed. In one aspect, a vehicle monitoring system is disclosed that includes a processor and a storage device storing instructions that, when executed by the processor, causes the processor to perform operations. The operations may include obtaining data generated by a vehicle monitoring component, determining whether the parked vehicle is permitted to navigate away from a location where the vehicle is parked, and in response to determining that the parked vehicle is not permitted to navigate away from the location, providing alert data to a processing unit installed within the parked vehicle, wherein processing of the generated alert data by the processing unit triggers a notification that is configured to alert the vehicle operator that the parked vehicle is not permitted to navigate away from the location.

Abstract: A monitoring system that is configured to monitor a includes a light device that is located at a pool of the property and that includes a camera that is configured to capture video data, and a monitoring control unit that is configured to receive, from the light device, the video data, determine that an object in the pool of the property is likely a person, based on determining that an object in the pool of the property is likely a person, determine a confidence score that reflects a likelihood that the person is swimming, determine that the confidence score does not satisfy a confidence score criteria, and perform a monitoring system action based on determining that the confidence score does not satisfy the confidence score criteria.

Abstract: Methods and apparatus are disclosed for enhancing urban surface model with image data obtained from a satellite image. Three dimensional models of an urban cityscape obtained from digital surface models may comprise surface location information but lack image information associated with the cityscape, such as the color and texture of building facades. The location of the satellite at the time of recording the satellite image interest may be obtained from metadata associated with the satellite image. A 3D model of a cityscape corresponding to the satellite image may be subjected to a transformation operation to determine portions of the 3D model that are viewable from a location corresponding to the location of the satellite when taking the picture. Visible facades buildings of the 3D model may be identified and mapped to portions of the satellite image which may then be used in rendering 2D images from the 3D model.
