1. A method comprising:

  • generating a first set of vectors by dividing an image into pixel blocks and transforming pixel values from the pixel blocks, a first vector of the first set being generated from a pixel block among the pixel blocks;

    encoding the first set of vectors into a second set of vectors, a second vector of the second set being an encoded representation of the first vector;

    generating a first array of ordered pairs, a first ordered pair of the first array pairing a value from the second vector with an index of the second vector, the index indicating the pixel block;

    using a processor, generating a second array of ordered pairs, a second ordered pair of the second array pairing the value with the first vector; and

    storing the second array as a feature vector of the image.
