基于融合特征的近似图像检测方法，， 提出了一种图像的融合特征提取方法， 融合特征相比单一的局部特征具有更

好的鲁棒性， 还实现了图像特征的加速匹配， 同时融合特征减少了存贮空间-Based the approximate image fusion detection method, proposed an image fusion feature extraction methods, the Fusion has better robustness characteristics compared to a single local feature, also accelerated image features match, at the same time reduced fusion features the storage space
