2014-10-19 10:31:54 -0600 | answered a question | Exception of cv::Exception not clear enough This could solved by checking the rootpath and make it empty if such exception occurs. |
2014-10-19 10:29:24 -0600 | asked a question | Does opencv provide dense features extraction algorithm on face recognition? I thought some dense feature is useful for 2D detection and object classification. Such method could be DENSE SIFT, hidimLBP and advanced learnd features, I thought these features can be adapted for many 2D application if such work is worthful |
2014-10-19 08:46:27 -0600 | answered a question | crop patch around SIFT point The octave is usually been set as 8 and there are also different scales of the original picture, this could be regard as filtered be different Gaussian filters. The patch I saw most is set as 44 or 22, each contains 44--66 pixals. |
2014-10-18 21:48:58 -0600 | answered a question | Classification using SVM Maybe you could train the caegory which isn't digt the 11th catogory, or use a two step SVM the filter them |
2014-10-18 21:45:39 -0600 | asked a question | The SVM kernel type couldn't be set as precomputed kernel ? I would like to use it in local linea svm, but it's incovenient without precomputed kernel. How to solve the problem? |
