Claim One:
1. A global descriptor vocabulary system comprising: a recognition module programmed to perform the step of obtaining 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 module and programmed to perform the steps of: obtaining the plurality of descriptor sets; clustering the plurality of descriptor sets into regions within the descriptor space; partitioning the descriptor space into a plurality of cells as a function of the clustered regions; assigning 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 of the assigned indices is of a number of bytes selected based on the amount of cells comprising the plurality of cells; and instantiating a global vocabulary module as a function of the assigned indices and representative descriptors and configured to generate a set of content indices that reference corresponding cells in the descriptor space based on an input set of descriptors.
