2015-03-05 07:03:29 -0600 | asked a question | Cannot generate matlab bindings in OpenCV Hi I am trying to compile OpenCV on 64bit ubuntu system having Matlab R2014b(64bit) with gcc 4.9.x. I use the following cmake parameters:
But during the configuration, I get the following message:
I have checked that I can compile mex files from within Matlab. All other modules are generated in the build directory except the matlab bindings. I have also seen the question: Bindings to access openCV from MATLAB do not generate. But no working solution is there. I have put the output of cmake at http://pastebin.com/rWcttkTU How can I proceed now ? (FYI, I don't have Computer Vision Toolbox in Matlab if that matters) EDIT: I report same behaviour with both OpenCV-3.0.0 beta and opencv-master(from github). |

2014-12-27 08:40:49 -0600 | asked a question | How to compile nonfree module in opencv 3.0 beta ? I have compiled opencv using the instructions at http://docs.opencv.org/doc/tutorials/... but there is no support for SIFT or SURF. I searched them in the install directory, but they are not there. I had tried the same instructions with opencv-2.4.9 and nonfree modules did compile. How to achieve the same with opencv 3.0 ? |

2014-09-21 02:21:51 -0600 | asked a question | using SIFT source code in OpenCV ? Is openCV using OpenSIFT. If yes, if I have to modify SIFT code for some of my research, should I use it from within OpenCV or directly use OpenSIFT ? |
2014-07-29 04:16:18 -0600 | asked a question | Develop for OpenCV using an IDE Hi I have started studying OpenCV source code. I was just wondering can opencv be setup in an IDE for Development ? It helps in finding related classes and functions, somewhat easier. (I am using QtCreator but any IDE would ease the understanding of code) |
2013-11-09 12:30:52 -0600 | asked a question | Why does opencv doesn't have PCA-SIFT ? PCA-SIFT is very robust, comparable to SIFT and described by lesser dimensions than SIFT. Just wondering why it is not included in OpenCV. |
2013-10-26 05:25:51 -0600 | asked a question | How to use PCA SIFT in opencv ? How can I use [PCA-SIFT] with the usual datatypes used in OpenCV for feature matching like Keypoint ? |
2013-10-26 01:00:58 -0600 | asked a question | Image matching using SIFT and BRIEF I am trying to match images using SIFT keypoint detector and BRIEF descriptor. The matching is done using Flann LSHIndexParams. I give one image as input, and it is compared against 20 other images. To store the matched image, I use the drawMatches function. It works perfectly for a few of the images, but after a few iterations gives this error:
My code is as follows: } |
2013-09-06 13:39:35 -0600 | asked a question | How to Determine perspective transform between two images I have transformed an image by using affine transform by using the function getAffineTransform() by manually passing 3 points for each image. (i.e. I know the affine transform) Now, I would like to obtain a homogenous matrix of the transform. How is it possible ? The reason, I am doing it is that I am trying to determine the false positives by extracting the features using SURF and matching using FLANN based Matcher . So, if I can get the homogenous transform between the two images, I can just compare the output of warpperspective on original keypoints and the matched keypoints. |
2013-09-06 10:53:47 -0600 | asked a question | unknown dot on using FileStorage to write Mat I am using the following code to store Mat(SURF features) to a file for reading the file, I use The Mat is stored and read as: {3., 6., 0., 0., 0., 0., 3., 2., 0., 0., 34.} //Note the .(dot) at the end of each number while before storing if I do cout << descriptors, it prints the same numbers without the dots. What is wrong with my code ? |

2013-09-02 10:57:16 -0600 | asked a question | What does function evaluateFeatureDetector do ? Hi I was looking at the descriptor extractor matcher tutorial . There a function is used "evaluateFeatureDetector" which calculates repeatibility and correspondence point. What exactly this function does, I am not able to find any reference in the documentation as well. |
2013-09-02 10:53:03 -0600 | commented answer | how to achieve Similarity Transform ? thanks. I have tried getAffineTransform(). Is it possible to get homogenous matrix from it ? |

2013-09-01 10:18:35 -0600 | asked a question | how to achieve Similarity Transform ? Hi I have been able to transform an image using affine transform and perspective transform using the affine transformation tutorial. I have also been able to rotate an image using getRotationMatrix2D. But how can I translate an image ? |
