1. A global descriptor vocabulary system comprising:

  • a recognition system configured to obtain a plurality of descriptor sets including descriptors associated with a plurality of digital representations of objects, each descriptor set existing within a descriptor space; and

    a vocabulary generation engine coupled with the recognition system and configured to;

    cluster the plurality of descriptor sets into regions within the descriptor space;

    partition the descriptor space into a plurality of cells as a function of the clustered regions;

    assign an index to each cell of the plurality of cells as a function of a representative descriptor in each cell of the plurality of cells, the representative descriptor being derived from a selected actual descriptor from the plurality of descriptor sets that is closest to an average of all descriptors in a corresponding cell of the descriptor space, wherein each one of the assigned indices comprises a cell address string selected as a function of an amount of cells comprising the plurality of cells; and

    instantiate a global vocabulary system as a function of the assigned indices and representative descriptors such that the global vocabulary system is configured to generate a set of content indices that reference corresponding cells in the descriptor space based on an input set of descriptors.
