Image-processing apparatus, image-processing system, image-processing method, and storage medium

An image-processing method comprising causing a computer to:

• track an object which is a target in one or more time-series images;
• store tracking information including movement trajectories of one or more of the tracked objects in a predetermined storage;
• set a detection region for detecting passing through of the object on the basis of the movement trajectory of the object, on the image, in accordance with a user's operation;
• evaluate a setting mode for the detection region on the basis of the tracking information stored in the predetermined storage and the set detection region;
• and
• output the tracking information, stored in the predetermined storage, from an output unit configured to output information, in an output mode based on an evaluation result of the setting mode for the detection region,
• evaluate a setting mode for the detection region, for each movement trajectory selected by the user, according to a presence or absence of intersection between one or more movement trajectories and the detection region, the one or more movement trajectories being selected by the user from among movement trajectories of one or more of the objects included in the tracking information stored in the predetermined storage.

A non-transitory computer-readable storage medium having a program stored therein, the program causing a computer to execute:

• a process of tracking an object which is a target in one or more time-series images;
• a process of storing tracking information including movement trajectories of one or more of the tracked objects in a predetermined storage;
• a process of setting a detection region for detecting passing through of the object on the basis of the movement trajectory of the object, on the image, in accordance with a user's operation;
• a process of evaluating the setting mode for the detection region on the basis of the tracking information stored in the predetermined storage and the set detection region;
• and
• a process of outputting the tracking information, stored in the predetermined storage, from an output unit configured to output information, in an output mode based on an evaluation result of the setting mode for the detection region,
• a process of evaluating a setting mode for the detection region, for each movement trajectory selected by the user, according to as presence or absence of intersection between one or more movement trajectories and the detection region, the one or more movement trajectories being selected by the user from among movement trajectories of one or more of the objects included in the tracking information stored in the predetermined storage.
