This result confirms that the features obtained using ART have more discriminative power compared to features obtained using FD, GFD, and RCF. Figure 21 The separability measures comparing the ART, FD, GFD, and RCF shape descriptors.
The experimental results show that Multi-region Histogram (MRH) feature is more discriminative for face recognition compared to Local Binary Patterns (LBP) and raw pixel intensity.
In this study, we attempt to leverage the spatial information provided by the local feature detector to build a more discriminative global image representation compared with the original aggregated vectors.
On the USA dataset, gene markers were more discriminative than pathway markers based on mean, median, and PCA methods, but less discriminative compared to pathway markers based on the proposed method and the CORG method.
This measure would have been more appropriate for comparing the models, since, as previously mentioned, it is more discriminative, also in the light of the underlying test data.
Recently, a useful extension to this approach is introduced, namely, the local ternary patterns (LTP), that is observed to be more discriminative and invariant to image noise in near-uniform regions as compared to LBP [18].
In group A, rep-PCR typing was more discriminative than MLST, dividing the 25 ECOR group A strains into 19 RPTc, compared to only 10 STc.
Compared with Bianchi and Piva's approaches [13, 14], the proposed approach provides more accurate detection results due to (i) better estimation of the quantization error caused by shifted JPEG compression and (ii) more discriminative information investigated by the adaptive DCT mode selection approach in Section 4.1 compared with that only DC mode is investigated in [13].
Compared to RGB video, depth sequence is more insensitive to lighting changes and more discriminative due to its capability to catch geometric information of object.
Comparing Fig. 2 with Fig. 3, it can be concluded that the LTPD feature is more discriminative than LTSD feature.
