Image matching method based on straight line

The image registration method of the straight line based on that from the video database, indexed by a shape descriptor of the straight line based applied haneunge retrieve the model image having a shape similar to a query image descriptor is disclosed. And defining a binary relationship between the image registration method of the straight base is (a) a step of obtaining the line information from the query image and the model image, (b) the straight line of the query image of a straight line and the model image, ( characterized in that it comprises a step of obtaining a degree of similarity on the basis of the continuous relaxation with a step, and (d) balance coefficient to obtain a balance coefficient indicating the compatibility of the label pair - c) a node of the query image and the model image based on the binary relation do.
