Abstract: A method for free flow fever screening is presented. The method includes capturing (801) a plurality of frames from thermal data streams and visual data streams related to a same scene to define thermal data frames and visual data frames, detecting and tracking (803) a plurality of individuals moving in a free-flow setting within the visual data frames, and generating (805) a tracking identification for each individual of the plurality of individuals present in a field-of-view of the one or more cameras across several frames of the plurality of frames. The method further includes fusing (807) the thermal data frames and the visual data frames, measuring (809), by a fever-screener, a temperature of each individual of the plurality of individuals within and across the plurality of frames derived from the thermal data streams and the visual data streams, and generating (811) a notification when a temperature of an individual exceeds a predetermined threshold temperature.

Abstract: A computer-implemented method includes obtaining (1110) a usecase specification and a usecase runtime specification corresponding to the usecase. The usecase includes a plurality of applications each being associated with a micro-service providing a corresponding functionality within the usecase for performing a task. The method further includes managing (1120) execution of the usecase within a runtime system based on the usecase and usecase runtime specifications to perform the task by serving an on-demand query and dynamically scaling resources based on the on-demand query, including employing (1122) a batch helper server to implement the usecase specification to load dynamic application instances and connect the dynamic application instances to existing instances, and employing (1124) the batch helper server to implement a batch helper configuration to load nodes/machines for execution of the on-demand query.

Abstract: Systems and methods to specify and execute real-time streaming applications are provided. The method includes specifying (170) an application topology for an application including spouts, bolts, connections, a global hash table, and a topology manager. Each spout receives input data and each bolt transforms the input data, the global hash table allows in memory communication between each spout and bolt to others of the spouts and the bolts. The topology manager (805) manages the application topology. The method includes compiling (820) the application into a shared or static library for applications, and exporting a special symbol associated with the application. The runtime system (840) can be used to retrieve the application topology from the shared or static library based on the special symbol (825) and execute the application topology on a single node or distribute across multiple nodes.

Abstract: A computer-implemented method executed by at least one processor for reducing radial distortion errors in fish-eye images is presented. The method includes capturing (701) an image from a camera including distortions, detecting (703) arc-shaped edge segments in the image including the distortions, estimating (705) a main distortion parameter by fixing a distortion centerpoint in a middle of the image, estimating (707) the distortion centerpoint with the main distortion parameter, and obtaining (709) an undistorted version of the captured image by inverting the distortion model.

Abstract: Systems and methods for demographic determination using image recognition. The method includes analyzing an image (210) with a pre-trained lightweight neural network model (220), where the lightweight neural network model generates a confidence value, and comparing (230) the confidence value to a threshold value to determine if the pre-trained lightweight neural network model is sufficiently accurate. The method further includes analyzing the image with a pre-trained heavyweight neural network model (240) for the confidence value below the threshold value, wherein the pre-trained heavyweight neural network model (240) has above about one million trainable parameters and the pre-trained lightweight neural network model (220) has a number of trainable parameters below one tenth the heavyweight model (240), and displaying demographic data to a user on a user interface (170), wherein the user modifies store inventory based on the demographic data.

Abstract: Methods and systems for authentication include determining (606), at a first worker system, that a master system that stores a current authentication-list cannot be reached by a first network. Authentication is performed (610) on an authentication request using a previously stored copy of the authentication-list at the first worker system. The authentication includes facial recognition that is performed on detected face images for a first time window, before receiving the authentication request, and for a second time window, after receiving the authentication request. Authentication removes matching detected face images after completing an authentication request to prevent other individuals from using a same identifier. Access is granted (518) to a secured area responsive to the authentication.
