Method of retrieving video picture and apparatus therefor

Abstract

An apparatus for retrieving a video picture includes a decoder section for decoding a coded bit stream of video picture data representing an arbitrary shape object and including shape information and texture information, a retrieval condition input section for inputting a retrieval condition for retrieval of a desired picture, a retrieval section for retrieving a picture meeting the retrieval condition by using shape information of the object decoded by the decoder section, and a display section for outputting the retrieved result obtained by the retrieval section.

       11 . A method of retrieving a video picture, comprising the steps of: 
 decoding a coded bit stream of video data representing an arbitrary shape object and including shape information, texture information, and scene description information of a scene description object;    synthesizing a plurality of decoded objects in accordance with the scene description information;    displaying a synthesized scene obtained by the synthesizing step;    analyzing the scene description information;    comparing the information with a predetermined condition; and    selecting a frame meeting a predetermined condition as a representative frame.    
   
   
       12 - 21 . (canceled)  
   
   
       22 . An apparatus for retrieving a video picture, comprising: 
 a decoder section which decodes a coded bit stream of video data representing an arbitrary shape object and including shape information, texture information, and information of a scene description object;    a synthesizing section which synthesizes a plurality of decoded objects in accordance with the information of the scene description object;    a display unit which displays the synthesized scene; and    a selecting section which analyzes the scene description information, compares the information with a predetermined condition, and selects a frame meeting the predetermined condition as a representative frame.    
   
   
       23 . The method according to  claim 11 , wherein the predetermined condition is a condition indicating that when a specific object is closed up, a frame corresponding to a maximum area of the object is set as a representative frame.  
   
   
       24 . The apparatus according to  claim 22 , wherein the predetermined condition is a condition indicating that when a specific object is closed up, a frame corresponding to a maximum area of the object is set as a representative frame.
