surf

[EDIT] I have devised some code for image comparison. The matching part is still a bit flawed and I would love some assitance. The project can be found at - GitHub . I have these two images Img1 and Img2 : When I use the following command in openCV Mat img1 = Highgui.imread("mnt/sdcard/IMG-20121228.jpg"); Mat img2 = Highgui.imread("mnt/sdcard/IMG-20121228-1.jpg"); try{ double l2_norm = Core.norm( img1, img2 ); tv.setText(l2_norm+""); } catch(Exception e) { //image is not a duplicate } I get a double value for l2_norm. This double value varies for duplicate image pairs. But if the images are

I'm trying a simple thing like detector = cv2.SIFT() and get this bad error detector = cv2.SIFT() AttributeError: 'module' object has no attribute 'SIFT' I do not understand that because cv2 is installed. cv2.__version__ is $Rev: 4557 $ My system is Ubuntu 12.04. Maybe someone has got the same problem and could help me. EDIT: Long story short, testypypypy.py : import cv2 detector = cv2.SIFT() ERROR: Traceback (most recent call last): File "testypypy.py", line 3, in <module> detector = cv2.SIFT() AttributeError: 'module' object has no attribute 'SIFT If I take SURF it works because SURF is in

I have built the openCV 3.0 alpha version from source with support for CUDA and TBB. Now, I want to do feature detection and feature matching using SURF algorithm. SurfFeatureDetector is present in the include file opencv2/nonfree/features2d.hpp & opencv2/nonfree/features2d.hpp But the module nonfree is missing in this version of openCV. I tried checking the opencv forums at answers.opencv.org but the site is under construction. How to use the non free modules? with opencv3.0, SURF/SIFT and some other things have been moved to a seperate opencv_contrib repo . you will have to download that,
