...For ethnicity classification [36, 5, 26, 7, 34, 1], it is crucial that the researchers obtain a balanced database with subjects from all ethnic groups(1) equally pre1 As is commonly adopted in the literature, the classification of ethnicity boils down to the 3-class case (asian, black and white), or the 4-class case (east asian, south asian,...

...Despite the wide literature on soft biometric trait classification [30, 22, 9, 24, 13, 28, 4, 16, 32, 29, 6, 23, 5, 10, 19, 33] and head pose estimation [25, 31, 1, 26, 3, 8], most of these approaches are not built for unconstrained environments (see Section 2 for details)....

...It is interesting to note that the maximum performance of PCA is higher than the best results obtained by PCA+LDA, PCA+SDA, and PCA+SVM. • Even though the input to LDA, SDA and SVM are dimensionality reduced principal components, these three algorithms are able to find good decision boundaries with large number of PCA components whereas PCA is providing very low accuracy for the same....

...With 10 PCA features, PCA+SVM is not able to learn the classifier, however, for 20-100 PCA features, the performance is increasing and is in the range of 78- 86%....
