....Fourier 217 Fig. 3. Segmentation of the nucleus of various cells. The cells in each row belong to the same class: CLL, FCC, MCL, and Normal, respectively transform, also considers as reference the semi major axis of the first harmonic locus to compensate for different rotations and starting points [29]. Scale invariance is obtained by normalizing each Fourier coefficient by the magnitude of the semi major axis, when the first harmonic locus is elliptic, and by the magnitude of the radius, when the first harmonic locus is circular. To obtain translation invariance, the bias terms are removed ....
