2013-10-29 04:04:04 -0600 | asked a question | matcher tutorial hi all... was following the matching tutorial at: http://docs.opencv.org/doc/tutorials/features2d/feature_homography/feature_homography.html#feature-homography i pretty much used the same code but the results with my own images are not that great. as you can see on the image bellow the mapped key points are not really as densely located as with the example box images. is there a special procedure to follow to prepare the images prior to using this code? i did use grayscale pngs as the example box.png and box_in_scene.png... here is my result: http://el.net/img/tmp/result.png thanks... (also whenever writing a title for a question here an annoying suggest menu is showing up and no matter what or where i am clicking it does not disappear. it just pushes the text of the message to the right) |

2013-10-27 22:08:33 -0600 | asked a question | brief_match_test so hi... i just installed the opencv 2.4.6.1 and compiled the brief_match_test in cpp samples. when i run it with the example images provided (box.png box_in_scene.png) i get :
i get that it checks if that expression is true. but if that is the stock code - i haven't changed anything in either the brief_match_test code or the matrix.cpp - and images provided with the samples why would that expression be a problem.. |
2013-06-04 01:45:41 -0600 | answered a question | Undefined symbols for architecture x86_64: helo... i'm having the same Undefined symbols for architecture x86_64 problem. like this: this i get when trying to compile an example opencv2 code from the 2.4.5 page. just installed it via cmake on os x 10.8.3. was trying xcode by setting up the build settings: using stdlib and correct include and lib paths. linker is complaining about - apparently according to the answer here above - a 32 bit system. but it's wrong: i'm really getting tired of trying to compile a simple opencv example on os x with xcode. or without xcode. i built and rebuilt everything a few times. had 2.4.2 and now 2.4.5 and always the same crap: Undefined symbols for architecture x86_64 i'd appreciate some help with this. thanks.... |
