An Efficient Wide-Baseline Dense Matching Descriptor
Yanli Wan, Zhenjiang Miao, Zhen Tang, Lili Wan, Zhe Wang · IEICE Transactions on Information and Systems · 2012
This letter proposes an efficient local descriptor for wide-baseline dense matching. It improves the existing Daisy descriptor by combining intensity-based Haar wavelet response with a new color-based ratio model. The color ratio model is invariant to changes of viewing direction, object geometry, and the direction, intensity and spectral power distribution of the illumination. The experiments show that our descriptor has high discriminative power and robustness.
