Hausdorff距离匹配代码
- Hausdorff距离匹配代码，实现了CANNY边缘特征点、HARRIS特征点、SIFT特征点、SURF特征点的Hausdorff距离匹配
ComputerVision-Problems-master
- Contains three problems - Texture Classification using k means and Laws filters, Vehicle Classification using SIFT and SURF features and BOWs approach and Edge Detection techniques
双线性插值
- 利用双线性插值，获取亚像素位置的灰度值。适用于得到sift、surf得到的特征点坐标处的灰度值获取(The gray value of sub-pixel position is obtained by bilinear interpolation)
ASIFT_slides_20min_v5
- ASIFT算法就是为了解决SIFT、ORB、SURF等特征描述算子倾斜匹配的问题。上面的这些算法可以很好的应对尺度、旋转情况下的匹配，但是对于倾斜影像的特征点匹配只能提取很少量的特征，所以作者提出ASIFT来解决这个问题。(If a physical object has a smooth or piecewise smooth boundary, its images obtained by cameras in varying positions undergo smooth apparen
