Table 1. Steps of MGOWLD feature extraction

Input:palmprint image IOutput:feature vector F

1. Utilize Eq.(13)--Eq.(16) to generate Gabor filters G_u_,_v with V scales and U orientations2. Image I is filtered by G_u_,_v,and utilize Eq.(18)--Eq.(19) to generate energy maps E_v and orientation maps O_v3. Following operations are performed on energy maps and orientation maps of each scale: 3.1 E_v and O_v are divided into N non-overlapping regions,and each region is recorded as

E_{v}^{(n)}

and

O_{v}^{(n)}

,respectively 3.2 Utilize Eq.(21)--Eq.(24) to calculate differential excitation ξ

_{m}^{(n)}

for each

E_{v}^{(n)}

3.3 Obtain statistics of feature histogram

\{H_{MGOWLD}^{(n)} (ξ_{m}^{(n)}, O_{v}^{(n)})\}

for each differential excitation ξ

_{m}^{(n)}

and orientation

O_{v}^{(n)}

3.4 Each column of

\{H_{MGOWLD}^{(n)} (ξ_{m}^{(n)}, O_{v}^{(n)})\}

is connected to form one-dimensional feature vector f_n 3.5 Concatenate the feature vector f_n of each block to form vector F_v=

[f_{1}, f_{2}, \dots, f_{N}]

as the feature of scale v4. Feature vectors F_v of all scales are connected to form the feature vector F=

[F_{1}, F_{2}, \dots, F_{V}]
