2015-09-09 04:02:13 -0600 | asked a question | Flann with large image database (>10000 images) I am trying to build a image search system where I have a database of over 10000 images. I'm extracting AKAZE descriptors of all the images and taking 500 best points. I construct a large matrix of my image database and then pass it to Flann Index class. Then I am able to run a image search on my database. The problem is, this method works fine if database is small than 2000 images with each image having < 500 keypoints. But when I use this with a larger database of over 3000 images, it won't give me proper matches. PS : I'm using autotunedindex values. |

2015-09-03 10:34:51 -0600 | commented question | can't find OpenCV 3 lib and bin files I have tried to follow those steps, but I'm stuck at this point : http://docs.opencv.org/3.0-beta/_imag... I can't find these .lib file inside the build folder. These files are included in opencv2 build., but in opencv3 they are unavailable! |

2015-09-03 05:24:54 -0600 | asked a question | can't find OpenCV 3 lib and bin files Hi, I need to try out the newly added KAZE features so I'm trying to switch from opencv 2 to opencv 3, but I can't find the dll and lib files in the x64 directory as I did with opencv2. x64/vc12/bin now only contains opencvworld and ffmpeg dlls. All other dlls and libs like features2d, flann and missing. Where can I find these dlls? I need to include these in a visual studio 2013 c++ project. |
2015-08-20 04:27:09 -0600 | commented question | Flann against a database of images I have a set of 100 images in a database. Now when I scan the same image using my mobile phone, it should take extract features of the scanned image and the features of images which are in the database and compare whether the scanned image is available in the database, if it is available it should tell, which image was scanned. That's what I meant by image recognition. I was extracting features of all the images and building one large matrix of descriptions and passing the matrix to Flann Index for knnSearch. This way I didn't have to worry about number of descriptions in each image. I'll try KAZE features. |
2015-08-20 01:47:51 -0600 | asked a question | Flann against a database of images Hi, I am trying to build a image recognition system where users upload images to a web portal and then they can scan that image in a mobile phone and upon successful recognition, mobile displays some content to the user. I have tried using FlannIndex with SURF, but since SURF is patented I can not use it in my application. So I started looking for FAST features with FREAK descriptor. I have built the descriptors for all the images using FREAK, but the problem is when I pass all the image descriptors to FlannBasedMatcher and it identifies any matches, how do I know the matched descriptors belong to which image in the database? Has anyone tried doing this before? Any help would be much appreciated. Thank you so much! |
