DURATION AND POTENTIAL REGION OF INTEREST FOR SUSPICIOUS ACTIVITIES - A simplified explanation of the abstract

This abstract first appeared for US patent application 18232258 titled 'DURATION AND POTENTIAL REGION OF INTEREST FOR SUSPICIOUS ACTIVITIES

Simplified Explanation

The patent application describes a method for analyzing a sequence of images to determine the paths of a target subject and a related subject. The method involves:

• Identifying the coordinates of the target subject and the related subject in multiple appearances within the images.
• Using these coordinates to define paths for both the target subject and the related subject.
• Calculating the minimum distances between the two paths to identify a region of interest.
• Determining the timestamps of the first and last appearances of both the target subject and the related subject.

The innovation in this patent application lies in the method for analyzing the paths of subjects within a sequence of images. This can have applications in various fields such as surveillance, object tracking, and behavior analysis.

Original Abstract Submitted

The method comprising determining a set of coordinates each for two or more appearances of a target subject within a sequence of images, the set of coordinates of the two or more appearances of the target subject defining a first path; determining a set of coordinates each for two or more appearances of a related subject within a sequence of images, the related subject relating to the target subject, the set of coordinates of the two or more appearances of the related subject defining a second path; determining one or more minimum distances between the first path and the second path so as to determine at least a region of interest; determining a timestamp of a first appearance and a timestamp of a last appearance of the target subject; and determining a timestamp of a first appearance and a timestamp of a last appearance of the related subject.
