Having thoroughly researched the existing palm print identification technology, in this paper, we propose a hierarchical multi-feature scheme to facilitate coarse-to-fine matching for efficient and effective palm print recognition. In our approach, first of all, we define two levels of feature: geometry feature based on distance (level-1 feature) and texture feature based on Zernike moment (level-...
H.264 can provide both objective and subjective image quality superior to existing standards by adopting new technical developments. But these developments increase the complexity and computation load of motion estimation greatly and make the encoder too complex to be applied in real-time applications. Although many fast algorithms are proposed, most of them would easily be trapped into local minimum...
