  • Geometrical transformation identifying system
    Patent number: 6671386
    Abstract: A geometrical correction system and method comprising creation of at least one pattern consisting of asymmetric two dimensional waves, embedding at least one pattern consisting of asymmetric two dimensional waves in a real domain, and calculation of at least one geometrical transformation applied by way of extraction of the embedded two dimensional waves. Said creation of at least one pattern consisting of asymmetric two dimensional waves means to calculate a two dimensional wave parameter set for creating at least one pattern adapted for use in the geometrical correction system of this invention. Also, said embedding of at least one pattern consisting of asymmetric two dimensional waves in a real domain means to add the pattern to an original image.
