I am currently testing Flann feature matching with OpenCV in python, and do not fully understand what some of the parameters actually do. Here is a snippet of code copied from the OpenCV docs. The ...

When I tried to use drawMatchesKnn function as mentioned in this tutorial for FLANN feature matching, I get the following error AttributeError: 'module' object has no attribute 'drawMatchesKnn' ...

I am currently trying to implement ORB with FLANN, I have read the documentation and it said that when using ORB with FLANN I have to use: index_params= dict(algorithm = FLANN_INDEX_LSH, table_nu...

I have a piece of code for matching features between a movie clip and a reference image. It generally works well, but sometimes it throws an error in the middle of a clip. Since it's always in the ...

I am using OpenCV 3.2 I am trying to use FLANN to match features descriptors in a faster way than brute force. // Ratio to the second neighbor to consider a good match. #define RATIO 0.75 void m...

I am running Ubuntu 14.04. I am trying to run FLANN with openCV 3 but I get an error. Everything bellow was tried by using AKAZE and ORB but the code if from my attempt to use ORB. I use ORB to f...

I am working on an image search project for which i have defined/extracted the key point features using my own algorithm. Initially i extracted only single feature and tried to match using cv2.Flan...

I have a panorama image, and a smaller image of buildings seen within that panorama image. What I want to do is recognise if the buildings in that smaller image are in that panorama image, and how ...

In python, OpenCV's FlannBasedMatcher constructor takes a dictionary of parametres, the first of which is algorithm. The python tutorial suggests that one can specify different values of algorithm ...

I am trying to scale the "matching_to_many_images.cpp" for large set of images. (20K+ images) https://github.com/kipr/opencv/blob/master/samples/cpp/matching_to_many_images.cpp I use FLANN based m...

I want to use a flann-based matcher in Python as described in http://opencv-python-tutroals.readthedocs.org/en/latest/py_tutorials/py_feature2d/py_matcher/py_matcher.html Since I am using OpenCV 3...

In my opencv project, I want to detect copy-move forgery in an image. I know how to use the opencv FLANN for feature matching in 2 different image, but I am become so confused on how to use FLANN f...

Trying to build PCL on VS2012 in Windows 8.1 so I can attempt to integrate my Kinect for Windows v2 sensor with it, however I seem to be running into a bunch of CMake errors that I don't know what ...

[Request you to read question details before marking it duplicate or down-voting it. I have searched thoroughly and couldn't find a solution and hence posting the question here.] I am trying to co...

How can I optimise the SIFT feature matching for many pictures using FLANN? I have a working example taken from the Python OpenCV docs. However this is comparing one image with another and it's sl...

The point of the application is to recognize an image from an already set list of images. The list of images have had their SIFT descriptors extracted and saved in files. Nothing interesting here: ...

I was wandering what the best approach would be for detecting 'figures' in an array of 2D points. In this example I have two 'templates'. Figure 1 is a template and figure 2 is a template. Each of...
