it depressing see long error message lol. have feeling maybe did not install rails correctly. please guide.

what seeing called stack trace. simplest of errors, can used track down issue is. there's nothing wrong installation, useful information!

as can see, in full error, 8 lines in, tells file, , line on.

/users/my/desktop/sites/simple_cms/db/migrate/20150321034322_alter_users.rb:6:in `up'

if error wasn't on purpose, you'd grateful little bit of information track down!

i want check scene image against 2 train images. that, detect features , compute descriptors of both training images. before detecting, computing , matching scene image, delete matches of train1 , train2. because these matches won't facilitate matching of scene image train1 , train2. so, match train1 train2 , vector of matches trainidx , queryidx. how can delete these matches in keypoints-vector , descriptor matrix of train1 , train2? best regards, dwi i have done below: std::vector<cv::keypoint> keypoints[2]; cv::mat descriptor[2]; std::vector< cv::dmatch > matches; /* write code generate keypoints, descriptors , matches here... keypoint[0] -> train image 1 keypoints keypoint[1] -> train image 2 keypoints descriptor[0] -> train image 1 descriptors descriptor[1] -> train image 2 descriptors matches -> matched between train image 1 , 2 */ // logic keep unmatched keypoints , corresponding descriptor
