I began training a cascade classifier
opencv_traincascade -data cascade -bg neg.txt -vec pos.vec -numPos 1000 -numNeg 1000 -w 48 -h 48
and partway in I killed the program, giving me intermediate output:
$ ls cascade/
params.xml
stage0.xml
stage1.xml
stage2.xml
stage3.xml
stage4.xml
stage5.xml
Now I would like to convert this into an XML file. I tried to use c-example-convert_cascade
c-example-convert_cascade --size="48x48" ./cascade cascade.xml
But got the following error:
OpenCV Error: Parsing error (./cascade(0): Valid XML should start with '') in icvXMLParse, file /home/jmuncaster/OutsideSource/opencv/modules/core/src/persistence.cpp, line 2227 terminate called after throwing an instance of 'cv::Exception' what(): /home/jmuncaster/OutsideSource/opencv/modules/core/src/persistence.cpp:2227: error: (-212) ./cascade(0): Valid XML should start with '' in function icvXMLParse
Question: How do I convert the intermediate output to an XML file readable by cv::CascadeClassifier?
