  • Patent number: 11734343
    Abstract: A computer vision processor of a camera extracts attributes of persons or vehicles from hyperzooms generated from image frames. The hyperzooms represent traffic patterns. The extracting is performed using a feature extractor of an on-camera convolutional neural network (CNN) including an inverted residual structure. The attributes include at least colors of clothing of the persons or colors of the vehicles. Mobile semantic segmentation models of the CNN are generated using the hyperzooms and the attributes. Attribute analytics are generated by executing the mobile semantic segmentation models while obviating network usage by the camera. The attribute analytics are stored in a key-value database located on a memory card of the camera. A query is received from the server instance specifying one or more of the attributes. The attribute analytics are filtered using the one or more of the attributes to obtain a portion of the traffic patterns.

  • Patent number: 11594043
    Abstract: A computer vision processor of a camera generates hyperzooms for persons or vehicles from image frames captured by the camera. The hyperzooms include a first hyperzoom associated with the persons or vehicles. The computer vision processor tracks traffic patterns of the persons or vehicles while obviating network usage by the camera by predicting positions of the persons or vehicles using a Kalman Filter from the first hyperzoom. The persons or vehicles are detected in the second hyperzoom. The positions of the persons or vehicles are updated based on detecting the persons or vehicles in the second hyperzoom. The first hyperzoom is removed from the camera. Tracks of the persons or vehicles are generated based on the updated positions. The second hyperzoom is removed from the camera. Track metadata is generated from the tracks for storing in a key-value database located on a non-transitory computer-readable storage medium of the camera.

  • Patent number: 10616255
    Abstract: A mobile device generates a first representation, based on a model, of a first content received by the mobile device from a website. An online system receives the representation of the content from the mobile device. The online system receives a second content from the website and generates a representation of the second content using the model. The online system compares the representation of the first content with the representation of the second content to determine a distance between the two representations. The distance indicates a level of similarity between the first content and the second content. The online system compares the distance between the representation of the first content and representation of the second content to determine if the distance exceeds a threshold distance. If the distance exceeds the threshold distance, the online system prevents other mobile devices from accessing the website.

  • Patent number: 10616274
    Abstract: An online system transmits to a mobile device a feed story that includes a uniform resource locator (URL) of a feed story website. The online system receives from the mobile device a URL log that includes URLs that the mobile device accessed in response to requesting content from the feed story website. The online system extracts a feature of at least one URL in the log, and inputs the extracted feature into a model that was trained, using machine learning, to identify websites that perform cloaking. The model generates a score indicating a likelihood that the feed story website performs cloaking based the extracted feature. The online system compares the score to a threshold to determine whether the feed story website performs cloaking. If the online system determines that the feed story website performs cloaking, the online system limits delivery of content including the URL of the feed story website.
