Apparatus and method for recognizing objects using filter information

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.

What is claimed is: 
     
         1 . A method for providing metadata related to an object, the method comprising:
 acquiring object image information comprising the object;   acquiring filter information for recognizing the object from 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.   
     
     
         2 . The method of  claims 1 ,
 wherein the filter information comprises outline image data showing an outline of the object.   
     
     
         3 . The method of  claim 1 ,
 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.   
     
     
         4 . The method of  claim 1 , wherein the acquiring 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.   
     
     
         5 . 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.   
     
     
         6 . 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. 
     
     
         7 . 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.   
     
     
         8 . 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 acquire filter information, the filter information to recognize an object from the object image information;   a control unit to recognize the object in the object image information using the filter information, and to acquire metadata related to the recognized object; and   an output unit to output the object image information, and the metadata in association with the object.   
     
     
         9 . The apparatus of  claim 8 ,
 wherein the filter information comprises outline image data showing an outline of the object.   
     
     
         10 . The apparatus of  claim 9 ,
 wherein the output unit outputs the filter information to overlap the object image information.   
     
     
         11 . The apparatus of  claim 8 ,
 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.   
     
     
         12 . The apparatus of  claim 8 , wherein the output unit outputs the metadata according to a predetermined priority if two or more pieces of metadata for the object are found. 
     
     
         13 . A method for recognizing an object, the method comprising:
 acquiring object image information comprising an object;   acquiring filter information for recognizing the object from the object image information;   detecting two or more candidates of the object using the filter information;   outputting the two or more candidates of the object; and   recognizing selected one of the candidates of the object as the object.   
     
     
         14 . The method of  claim 13 , further comprising:
 acquiring the metadata related to the object; and   outputting the metadata in association with the object.   
     
     
         15 . The method of  claim 13 , the filter information comprises outline image data showing an outline of the object. 
     
     
         16 . A object recognizing 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 acquire filter information, the filter information to recognize an object from the object image information;   a control unit to detect two or more candidates of the object using the filter information, and to recognize selected one of the candidates of the object as the object; and   an output unit to output the object image information, and the two or more candidates of the object.   
     
     
         17 . The apparatus of  claim 16 ,
 wherein the control unit further acquires the metadata related to the object, and   wherein the output unit outputs the metadata in association with the object.   
     
     
         18 . The apparatus of  claim 16 , wherein the filter information comprises outline image data showing an outline of the object.
