... matching. Moreover, the local structure can tolerate some deformation because it is formed from only a small area of the fingerprint. So, the local structures can be directly used for matching ... Section 5. 2. The proposed framework example, the room of performance increasing is limited.

... of WZS is greater than that for lower temporal correlation sequences, such as Foreman ,for example, 3–4.5 dB PSNR gain for the former, as compared to 0.5–1 dB gain for the latter. To demonstrate ... bet- ter performance over MPEG-4 FGS for sequences with high temporal correlation and limited improvement for high- motion sequences.

Presum ably, micro-photon cages might be formed in the ... anodes, which could obviously enhance the DSSC performance. It must be pointed out that the real dominating factor(s) responsible for the performance enhancement of our F-DSSCs is still el...
