1. An image recognition method comprising:

  • an extraction step of extracting local feature elements in an input image;

    a conversion step of assembling the local feature elements extracted at said extraction step and generating array data from the local feature elements on the basis of a predetermined lattice pattern; and

    a matching step of estimating a resemblance between the local feature elements array data and a reference plurality of local feature elements array data stored in a memory by computing a differential value and selecting model array data for which the differential value is less than a predetermined threshold value.
