基于sift的图像拼接技术
应用背景
SIFT特征匹配算法, 在没有先验知识条件下, 对旋转、尺度缩放、光照、视角变化等图像变化因素保持一定鲁棒性, 且对低重叠区域(30%左右的相似重叠区域)、部分遮挡(只出现在其中一张图上的物体)和噪声等因素也保持较好的可匹配性。可用于多尺度下的特征匹配,以及鲁棒性的图像拼接。
关键技术
1.高斯尺度空间极值检测
2.特征点位置的确定
3.特征点方向的分配
4.生成SIFT特征向量
5.图像拼接
6.图像融合
提取图像的sift特征,构造特征描述子,基于sift特征构造BBF-tree,根据描述子之间的欧式距离进行初步的匹配,然后进过鲁棒的Ransac估计出最佳运动模型H,然后用距离加权的方法在重叠区进行融合。

A novel texture
A novel texture-based Automatic Fingerprint Authentication System (AFAS) is proposed. A fingerprint image is preprocessed to enhance the image by Short Time Fourier Transform (STFT) analysis. Then, three sets of invariant moment features, as a kind of texture features, are extracted from three different sizes of Region of Interest (ROI) areas based on the reference point from the enhanced fingerprint image. Each set of invariant moments contain seven invariant moments. Fingerprint verification is realized by Euclidean distance between the two corresponding features of the test fingerprint image and template fingerprint image in the database. -A novel texture-based Automatic Fingerprint Authentication System (AFAS) is proposed.
