Abstract
Systems and methods for determining dwell time is provided. The method includes receiving images of an area including one or more people from one or more cameras, and detecting a presence of each of the one or more people in the received images using a worker. The method further includes receiving by the worker digital facial features stored in a watch list from a master controller, and performing facial recognition and monitoring the dwell time of each of the one or more people. The method further includes determining if each of the one or more people is in the watch list or has exceeded a dwell time threshold.
Claims20
A computer implemented method for determining dwell time, comprising:
- receiving images of an area including one or more people from one or more cameras;
- detecting a presence of each of the one or more people in the received images using a worker;
- receiving by the worker digital facial features stored in a watch list from a master controller;
- performing facial recognition and monitoring the dwell time of each of the one or more people;
- and
- determining if each of the one or more people is in the watch list or has exceeded a dwell time threshold.
A system for dwell time determination, comprising:
- a master controller having one or more processors and memory, the master controller including a watch list and an alerts manager stored in the memory;
- a worker having one or more processors and memory, wherein the worker includes a dwell time calculator and a facial recognition neural network executable by the one or more processors;
- and
- a plurality of cameras in communication with the worker, wherein the worker receives video images from the plurality of cameras and performs facial recognition and dwell time calculations for each of one or more people detected in a field of view of each of the plurality of cameras, wherein the worker receives images of an area including one or more people from the plurality of cameras, and performs facial recognition and monitoring of a dwell time for each of the one or more people.
A non-transitory computer readable storage medium comprising a computer readable program for determining dwell time, wherein the computer readable program when executed on a computer causes the computer to perform:
- receiving images of an area including one or more people from one or more cameras;
- detecting a presence of each of the one or more people in the received images using a worker;
- receiving by the worker digital facial features stored in a watch list from a master controller;
- performing facial recognition and monitoring the dwell time of each of the one or more people;
- and
- determining if each of the one or more people is in the watch list or has exceeded a dwell time threshold.
