Abstract

An object recognition method using filter information includes acquiring object image information including an object of interest, acquiring filter information for recognizing the object of interest from the object image information, and recognizing the object of interest using the filter information. An object recognition apparatus using filter information including an object information acquiring unit to acquire object image information comprising an object of interest, a filter information input unit to acquire filter information, an output unit to output the image information and the filter information, and a controller to recognize the object of interest in the object image information using the filter information.

Claims

1. A method for providing metadata related to an object, the method comprising:

acquiring object image information comprising the object;

receiving, separate from the object image information, filter information for recognizing the object included in the object image information;

applying the filter information to the object image information;

recognizing the object using the filter information;

acquiring the metadata related to the object; and

outputting the metadata in association with the object,

wherein the recognizing of the object using the filter information comprises;

detecting object recognition information using the filter information, wherein the object recognition information comprises characteristic information corresponding to the object;

comparing the object recognition information with stored reference characteristic information; and

recognizing the object if the object recognition information matches the stored reference characteristic information,

wherein the filter information comprises outline image data showing an outline of the object.

2. The method of claim 1, wherein the receiving of the filter information comprises:

outputting the object image information;

receiving an outline image data of the object; and

outputting the outline image data to overlap the object image information.

3. The method of claim 1, further comprising:

outputting a request to input additional filter information if the object is not recognized using the filter information;

receiving additional filter information in response to the request; and

recognizing the object using the additional filter information.

4. The method of claim 1, wherein the outputting of the metadata comprises outputting the metadata according to a predetermined priority if two or more pieces of metadata for the object are found.

5. The method of claim 1, wherein the acquiring of the metadata related to the recognized object comprises:

requesting the metadata related to the recognized object via a network; and

receiving the metadata related to the recognized object from the network.

6. A metadata providing apparatus using filter information, the apparatus comprising:

an object information acquiring unit to acquire object image information comprising an object;

a filter information input unit to receive filter information separate from the object image information, the filter information to recognize an object included in the object image information, and to apply the filter information to the object image information;

a control unit comprising a processor configured with executable instructions to recognize the object using the filter information, and to acquire metadata related to the recognized object, wherein the control unit detects object recognition information using the filter information, the object recognition information comprising characteristic information corresponding to the object, compares the object recognition information with stored reference characteristic information, and recognizes the object if the object recognition information matches the stored reference characteristic information; and

an output unit to output the object image information and the metadata in association with the object,

wherein the filter information comprises outline image data showing an outline of the object.

7. The apparatus of claim 6, wherein the output unit outputs the filter information to overlap the object image information.

8. The apparatus of claim 6, wherein the output unit outputs the metadata according to a predetermined priority if two or more pieces of metadata for the object are found.

9. A method for recognizing an object, the method comprising:

acquiring object image information;

receiving, separate from the object image information, filter information;

applying the filter information to the object image information;

detecting two or more candidate objects included in the object image information based on the filter information;

outputting the detected candidate objects for selection;

selecting one of the candidate objects; and

recognizing the selected candidate object as a target object,

wherein detecting the two or more candidate objects based on the filter information comprises;

detecting object recognition information using the filter information, wherein the object recognition information comprises characteristic information corresponding to the two or more candidate objects;

comparing the object recognition information with stored reference characteristic information; and

recognizing the two or more candidate objects if the object recognition information matches the stored reference characteristic information,

wherein the filter information comprises outline image data showing an outline of the object.

10. The method of claim 9, further comprising:

acquiring the metadata related to the target object; and

outputting the metadata in association with the target object.

11. An object recognizing apparatus using filter information, the apparatus comprising:

an object information acquiring unit to acquire object image information;

a filter information input unit to receive filter information separate from the object image information, and to apply the filter information to the object image information;

a control unit comprising a processor configured with executable instruction to detect two or more candidate objects included in the object image information based on the filter information, to determine a selection of one of the candidate objects; and

to recognize the selected candidate object a target object, wherein the control unit detects object recognition information using the filter information, the object recognition information comprising characteristic information corresponding to the two or more candidate objects, compares the object recognition information with stored reference characteristic information, and recognizes the two or more candidate objects if the recognition information matches the stored reference characteristic information; and

an output unit to output the object image information, and the detected candidate objects,

wherein the filter information comprises outline image data showing an outline of the object.

12. The apparatus of claim 11, wherein the control unit further acquires the metadata related to the target object, and wherein the output unit outputs the metadata in association with the target object.
