¿µ¹®³»¿ë¿ä¾à The content-based retrieval technology gets more attention these days due to the advancement of image and video retrieval technology. TTA sets the standard on image retrieval, video retrieval and object-oriented image retrieval in mobile environment in 2010, 2011 and 2012 respectively. In this standard, performance evaluation criteria for the state-of-art video retrieval technology using object-oriented approach are described.
Object-oriented video retrieval is the technology that extracts the object from the video frames and then uses the features derived from the object and relations between the objects. Through this, more intuitive and accurate video retrieval is possible.
At present, no nation has ever established a standard for the object-based video retrieval and the relevant research has just begun.
The major items for the performance evaluation of object-based video retrieval are success rate, complexity, memory size, and the accuracy of object separation.
