英文摘要：

This paper proposes a template matching algorithm in Fourier transform domain （TMFT）, which is robust against geometrical transformations in spacial domain, and makes the template matching to be a prototype matching. Timeshifting of signal in time-domain is eliminated by time-shifting property of FT. Disturbance out of signal intensity is Normalized by the auto-correlativity R （0）. Energy distributive function is introduced to keep the correlation between templates and target against the rotation relative to template signal. The experiments show that TMFT assures the constancy in template matching and is available to rid the correlativity of geometrical change in time-domain.
