Thank you for your good work, I want to follow your create_voc.cc to train vocabulary, but I encounter an error.

In your code: cv::Mat desc_mat(cv::Size(32, pts.size(0)), CV_8UC1, desc.data()); Dose you use 32-D trained descriptors?

In addition, there is an error in training vocabulary: Creating vocabulary. May take some time ... Segmentation fault (core dumped)

@cumtchenchang Thanks for your question. Have you solved the problem?
