2015-12-13 05:59:34 -0500 asked a question how to initialize the Tracker several times using opencv_contrib?

I am using opencv_contrib for TLD tracking. Firstly, I use one algorithm to detect moving objects with moving camera. Then I want to track the detected objects. Sometimes the objects may be out of sight. So I decide to initialize the TLD tracker again. However, when I tried to use the Tracker->init() for second initialization, it always failed.

Also, I have read part of the source code about the tracker. There are two reasons that can lead to the failure. But I still do not know how to solve it except modifying the source code.

Can anyone help me? Looking forward to your advice!

When I tried to train svm classifier, I found there is no content in the xml file. Then I debug, I meet the error as following.
Can't find a source file at "/build/buildd/glibc-2.19/signal/../nptl/sysdeps/unix/sysv/linux/raise.c" Locate the file or edit the source lookup path to include its location.

It seems like I miss the target file, but I can't find the path in my computer. So I think it's caused by other reasons. Have you ever met the same error! If so, let's talk about it!

Yes. You are right! Thank you for your help.

Yeah. Because when I try to use svm.save(), I can't find the function. Maybe there is no this function in opencv3.0-beta. I'm also very confused.

In opencv3.0, we can code like following to train svm classifier.

Ptr<SVM> svm = StatModel::train<SVM>(trainingDataMat, ROW_SAMPLE, labelsMat,params);

However,there is no way to save the result as xml file. In the early version, we can use svm.save("svm.xml") to save the result. It's so convenient. So I want to know how to generate xml file of svm classifier using opencv3.0-beta. Thank you for your suggestions!

2015-02-02 02:06:15 -0500 asked a question can’t find the pdb(opencv_world300d.pdb)

When I want to find where the opencv_world300d.pdb is,I find that there is only the opencv_ts300d.pdb. So I think it may be the bug of the opencv3.0-beta.

What's the solution? Please help me. Thank you!
