Abstract
Provided are a re-wandering detecting device and method. The method includes: detecting an object and positional information about the object from an input image; determining whether the object wanders based on the positional information about the object; in response to determining that the object wanders, determining whether the object re-wanders by determining whether a database stores information about an object identical to the object detected from the input image; and providing information about wandering of the object according to whether the object re-wanders.
Claims20
A method of detecting re-wandering, the method comprising:
- detecting, by at least one processor, an object and positional information about the object from an input image;
- determining, by the processor, whether the object wanders based on the positional information about the object;
- in response to determining that the object wanders, determining whether the object re-wanders by determining whether a database stores information about an object identical to the object detected from the input image;
- and
- providing, by the processor, information about wandering of the object according to whether the object re-wanders,
- wherein the information is provided differently in accordance with a number of times of wandering by the object.
A re-wandering detecting device comprising at least one processor to implement:
- an object detector configured to detect an object and positional information about the object from an input image;
- a first wandering determiner configured to determine whether the object wanders based on the positional information about the object;
- a re-wandering determiner, in response to determining by the first wandering determiner that the object wanders, configured to determine whether the object has wandered more than one time by determining whether a database stores information about an object identical to the object detected from the input image;
- and
- an information provider configured to provide information about wandering of the object when the object wanders one time, and differently provide information about wandering of the object when the object wanders more than one time.
A method of detecting re-wandering, the method comprising:
- detecting, by at least one processor, an object and positional information about the object from an input image;
- determining, by the processor, whether the object wanders based on the positional information about the object;
- in response to determining that the object wanders, determining whether the object re-wanders by determining whether a database stores information about an object identical to the object detected from the input image;
- and
- providing, by the processor, information about wandering of the object according to whether the object re-wanders, wherein the input image is a motion picture comprising a plurality of frames,
- wherein the detecting the object comprises detecting the object and positional information about the object from each of the plurality of frames, and
- wherein, in the determining whether the object wanders, the object is determined as a wandering object if the object satisfies a preset wandering condition,
- wherein the wandering condition is that at least one closed curve is formed by a path of the object calculated using the positional information about the object.
A method of detecting re-wandering, the method comprising:
- detecting, by at least one processor, an object and positional information about the object from an input image;
- determining, by the processor, whether the object wanders based on the positional information about the object;
- in response to determining that the object wanders, determining whether the object re-wanders by determining whether a database stores information about an object identical to the object detected from the input image;
- and
- providing, by the processor, information about wandering of the object according to whether the object re-wanders,
- wherein the information is provided differently in accordance with a number of times of wandering by the object,
- wherein the detecting the object comprises detecting the object and positional information about the object from each of a plurality of frames, and
- wherein in response to determining that the object re-wanders, the providing the information comprises displaying images of the object detected in the detecting the object together with other images of the object stored in the database on a screen with reference to the positional information about the object.
