DURATION AND POTENTIAL REGION OF INTEREST FOR SUSPICIOUS ACTIVITIES - A simplified explanation of the abstract
This abstract first appeared for US patent application 18232260 titled 'DURATION AND POTENTIAL REGION OF INTEREST FOR SUSPICIOUS ACTIVITIES
Simplified Explanation
The abstract describes a method for analyzing sequences of images to determine the paths of a target subject and a related subject. The method calculates the minimum distances between the paths to identify a region of interest. It also determines the timestamps of the first and last appearances of both subjects.
- The method determines the paths of a target subject and a related subject in a sequence of images.
- It calculates the minimum distances between the paths to identify a region of interest.
- The method also determines the timestamps of the first and last appearances of both subjects.
Potential Applications
- Surveillance systems: This method can be used to track and analyze the movements of individuals or objects of interest in surveillance footage.
- Wildlife research: Researchers can use this method to study the behavior and interactions of animals in their natural habitats.
- Sports analysis: Coaches and analysts can apply this method to track the movements of players during games and training sessions.
Problems Solved
- Object tracking: The method solves the problem of accurately tracking the paths of multiple subjects in a sequence of images.
- Region of interest identification: By calculating the minimum distances between paths, the method helps identify specific areas or events of interest within the image sequence.
Benefits
- Efficiency: The method automates the process of tracking and analyzing subjects in image sequences, saving time and effort compared to manual methods.
- Accuracy: By determining the paths and timestamps of subjects, the method provides precise data for further analysis and understanding.
- Versatility: The method can be applied to various fields, including surveillance, wildlife research, and sports analysis, offering a wide range of potential applications.
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.
