    Abstract: Access control system and method to distinguish between tailgate and piggyback. The method includes receiving, from a camera positioned at an access point, one or more images of a first person at the access point and determining based on credential information whether the first person is authorized to enter through the access point. In response to determining that the first person is authorized to enter through the access point, the method includes determining, based on a consent-to-follow gesture of the first person detected in the one or more images, a number of guests of the first person requested to enter through the access point. The method also includes determining, based on the one or more images, a number of persons entering through the access point and generating an alert indicating unauthorized entry when the number of persons is greater than the number of guests.

    Abstract: One example temperature sensing device includes an electronic processor configured to receive a thermal image of a person captured by a thermal camera. The electronic processor is configured to determine a first temperature and a first location of a first hotspot on the person. The electronic processor is configured to determine a second location of a second hotspot on the person based on the second location being approximately symmetrical with respect to the first location about an axis, and the second hotspot having a second temperature that is approximately equal to the first temperature. The electronic processor is configured to determine a distance between the first location of the first hotspot and the second location of the second hotspot. In response to determining that the distance is within the predetermined range of distances, the electronic processor is configured to generate and output an estimated temperature of the person.

    Abstract: Systems for personalized intent prediction may perform a process including receiving image data depicting the behavior of a person on approach toward a secure location, generating intent data including data representing a current trajectory of the person on the current approach, comparing the intent data with a personal statistical model for the person that includes data representing trajectories associated with historical approaches by the person toward the secure location and respective result data indicating whether the historical approach resulted in the person entering the secure location, determining, dependent on the comparing, a personalized intent score representing a likelihood that the person intends to enter the secure location on the current approach, and pre-emptively enabling, or refraining from pre-emptively enabling, entry to the secure location prior to the person reaching the secure location based on whether the personalized intent score meets or exceeds a predetermined minimum confidence threshold for enabling entry.

    Abstract: Methods and systems for tamper reduction for camera systems. One example system includes a camera with a first field of view configured to operate in a low-power mode and an active mode, an energy wave sensor with a second field of view, and an electronic processor. The electronic processor is configured to monitor, via the energy wave sensor, for an object within the second field of view and determine an object type of the object. In response to determining that the object type is a vehicle, the electronic processor transitions the camera from the low-power mode to the active mode and captures, via the camera, an image of the vehicle. In response to determining that the object type is a person, the electronic processor performs a tamper-monitoring action when the person is within a first predetermined range of a plurality of predetermined ranges of the system.

    Abstract: Systems for detecting liveness in image data may perform a process including receiving, from one or more image capture devices, two-dimensional image data representing two images captured simultaneously and depicting the same human person, including data representing light captured in two spectral bands, such as visible light and infrared light. The received image data may be converted to grayscale or downsampled prior to further processing. The process may include creating a two-dimensional combined image representation of the received image data and analyzing the combined image representation to detect any implied three-dimensional features using a neural network or machine learning. The process may include classifying the received image data as likely to depict a live person or a two-dimensional spoof of a live person, dependent on the analysis, and outputting a classification result indicating a likelihood that the received image data depicts a live person.

    Abstract: A smart badge, and a method, system and computer program product for badge detection and compliance are disclosed. The method, carried out within a security system, includes capturing, using a camera, an image of a person. The captured image includes a face of the person within a first pixel region of the image. The method also includes performing facial recognition on the first pixel region to determine an identity of the person. The method also includes performing video analytics, on a second pixel region of the image, different than the first pixel region, to make a first determination that the identified person is wearing a badge, or to make a second determination that no badge is being properly worn by the identified person. The method also includes generating an alert, specific to the identified person, within the security system based at least in part on the first or second determination.

    Abstract: A computer implemented method, comprising: detecting presence of an object of interest within a plurality of image frames received from a sensor; determining that the object of interest is moving towards an automatic door that is configured to close within a predetermined time period; determining, based on position, speed and direction of the object of interest, a likelihood that the object of interest may impede closing of the automatic door; and when the likelihood exceeds a threshold value, maintaining the automatic door in an open position for a longer period of time than the predetermined time period.
