Automatic 3D Face Recognition Using Fourier Transform

One of the applications of the Fourier Transform is on 3D face recognition. The profiles are stored in terms of their Fourier Coefficients in order to minimize the size of input data. Dimension can be reduced on deformed circular curves and on the properties of Fourier Transform.

In order to minimize the input data, we compute the Fourier coefficients of the designated profiles and store it in a database, other than storing the actual points of the profile. Thus, having a database of images representing different individuals where each person is represented by two profiles stored by means of their Fourier’s.
