TRAJECTORY MAPPING - A NEW NONMETRIC SCALING TECHNIQUE

Trajectory mapping is a new scaling technique designed to recover the parameterizations, axes, and paths used to traverse a feature space. U nlike with multidimensional scaling, there is no assumption that the s pace is homogeneous or metric. Although some metric ordering informati on is obtained with trajectory mapping, the main output is the feature parameterizations that partition the given domain of object samples i nto different categories. After an introductory example, the technique is further illustrated by using first a set of colors and then a coll ection of textures.
