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

This abstract first appeared for US patent application 18232257 titled 'DURATION AND POTENTIAL REGION OF INTEREST FOR SUSPICIOUS ACTIVITIES

Simplified Explanation

The patent application describes a method for analyzing sequences of images to determine the paths of a target subject and a related subject. This information can be used to identify regions of interest and track the timestamps of appearances for both subjects.

• The method involves determining the coordinates of two or more appearances of a target subject and a related subject within a sequence of images.
• These coordinates are used to define paths for both subjects.
• The method then calculates the minimum distances between the two paths to identify regions of interest.
• Timestamps of the first and last appearances of both the target subject and the related subject are determined.
• This information can be used for various applications such as object tracking, surveillance, or analyzing patterns of movement.

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.
