1. A computer implemented method for searching a computer database for target objects that are similar to a known object comprising: determining if a target object in the computer database is similar with the known object by comparing a mathematical template associated with pixels that are based on a full-size of the known object with a matrix of numbers derived from pixels associated with the target object, wherein comparing the mathematical template associated with pixels that are based on the full-size of the known object with a matrix of numbers derived from pixels associated with the target object further comprises moving the mathematical template over the matrix of numbers from a first position to a second position.
