SiftySifty
SiftySifty is a open source library that extract SIFT keypoins from a image. Writed by pure c++ and does't need any other library.
Include
Only include extracting SIFT keypoints form a image, does't contains match and display. The SIFT algorithm ref:Lowe, D. Distinctive image features from scale-invariant keypoints. International Journal of Computer Vision, 60, 2 (2004), pp.91--110. Website:http://www.cs.ubc.ca/~lowe/keypoints/
Demo
Running The demo must need OpenCV. The demo includes display the keypoints on a image and match between with OpenCV.
Display SIFT keypoints by SiftySifty
the keypoints that draws in the image is detected by SiftySifty and displayed by OepnCV.
Math the images using SIFT keypoints by SiftySifty
the keypoints that draws in the image is detected by SiftySifty and matching&display is by OepnCV.
Math the images using SIFT keypoints by SiftySifty and OpenCV
math keypoints between SiftySifty and OpenCV, left is SiftySifty, right is OpenCV. Displayed by OepnCV.
