Abstract: The Fourier transformation played the very vital role in digital image processing. Feels the interest text character characteristic goal the localization is an essential technology, it mainly draws support from the Fourier pair digital image to carry on frequency range processing, then transforms to the air zone in carries on the image restructuring once more, because the energy mainly concentrates in the low frequency component, only withdraws demonstrated that the high energy region, will complete to feels the interest goal the pattern localization.
