Table 10 Dimensionality of the feature vectors of the ZM and LBP/LTP descriptors
From: Complementary feature sets for optimal face recognition
Approach | Size of the feature vector | Remarks |
|---|---|---|
ZMmag | 40 | For moments up to order nmax = 11 |
ZMmagPhase | 2 × 40 | Size of the feature vector is double the size of magnitude features |
ZMcomponent | 2 × 40 | Size of the feature vector is double the size of magnitude features |
LBP | 3,776 | Taking image patch size of 8 × 8 pixels for uniform local binary patterns |
LTP | 2 × 3,776 | Number of features is double the number of LBP features because two feature vectors consisting of the positive and the negative uniform binary patterns are taken |
