Claim 0:
1. A two-dimensional (2D) map generation apparatus for generating a 2D map in which a plurality of pieces of target information is plotted on a 2D plane based on a feature vector generated from target information, the apparatus comprising:
a feature vector computation unit that computes a feature vector from the target information,
a 2D processing unit that generates 2D latitude and longitude information by performing a dimension compression process on the feature vector; and
a map generation unit that generates the 2D map based on a plurality of pieces of latitude and longitude information generated by the 2D processing unit for the plurality of pieces of target information,
wherein
when m feature vectors are computed from m pieces of target information (m is an arbitrary integer of 2 or more) to generate the 2D map by dimensionally compressing the m feature vectors, and then the 2D map is regenerated by adding x pieces of target information (x is an arbitrary integer of 1 or more),
the feature vector computation unit re-computes the feature vector from m+x pieces of target information,
the 2D processing unit uses m pieces of latitude and longitude information generated from the m feature vectors as they are regarding to the m pieces of target information, and additionally generates, regarding to the x pieces of target information, x pieces of latitude and longitude information by performing a dimension compression process on x feature vectors computed from the m+x pieces of target information using a function having the same effect as when a dimension compression process is performed on the m feature vectors, and
the map generation unit generates the 2D map based on the m pieces of latitude and longitude information generated for the m pieces of target information and the x pieces of latitude and longitude information generated for the x pieces of target information by the 2D processing unit.
