SDO_GEOM.DTW_DISTANCE( s IN SDO_GEOMETRY, t IN SDO_GEOMETRY, w_in IN NUMBER default NULL ) RETURN NUMBER; Description Compares two different spatial trajectories by measuring the distance between the two objects. Parameters s The first two-dimensional line geometry. ...
To measure the DTW distance between two strings, one must "warp" them, that is, double some letters in the strings to obtain two equal-lengths strings, and then sum the distances between the letters in the corresponding positions. When the distances between letters are integers, we show that...
