Abstract: A method and system for tracking an object of interest in a talkgroup. The method includes receiving a first image stream including the object from a first portable communication device associated with the talkgroup. The method includes detecting the object in the first image stream, determining a first view angle associated with the object's position in relation to the first device, and determining a second view angle associated with the object's position in relation to a second portable communication device. When a difference between the first angle and the second angle is below a threshold, a first modified image stream is generated by highlighting the object in the first image stream. When the difference between the first angle and the second angle is above the threshold, a second modified image stream is generated by highlighting the object and indicating a relative direction to the object from the second device.

Abstract: Methods, and apparatus for managing a communication group. One method includes forming a communication group of one or more portable communications devices based on a first object of interest and identifying a second object of interest based on the first object of interest. The method also includes determining whether an image feed includes the second object of interest and when the image feed includes the second object of interest, adding a portable communications device associated with the image feed to the communication group.
