Patent Images

1. A process for recognizing known images of a plurality of objects, the process comprising:

  • (a) obtaining a plurality of different resolutions for an unknown image;

    (b) performing local autocorrelation for each resolution of the unknown image to produce a feature vector for each resolution;

    (c) performing linear discriminant analysis for each feature vector, wherein each feature vector from the local autocorrelation is processed employing a transformation matrix, the transformation matrix being calculated with respect to known images required to be recognized, the linear discriminant analysis producing a plurality of outputs;

    (d) performing fuzzy integration to merge the outputs from the linear discriminant analysis to produce a merged output for each of the known images, each merged output being indicative of similarity of the unknown image to each known image;

    (e) analyzing each merged output to identify a known image corresponding to the unknown image.
