I have a haarcascade file generated using opencv_traincascade which generates an xml file. The format of this xml file is different from that of generated by opencv_haartraining.
OpenCV documentation says that opencv_traincascade can save (export) a trained cascade in the older format. However, I have not found any way to do this.
I wanted to ask if anybody has any luck in converting a new format haarcascade xml file to the older format.
