I am using OpenCV 2.4.9 to try and build my own classifier. I am following the instructions on this site: http://coding-robin.de/2013/07/22/train-your-own-opencv-haar-classifier.html
I was successful in creating a classifier XML file. I went to try an build a new different classifier and ran into the following error:
Training parameters are loaded from the parameter file in data folder! Please empty the data folder if you want to use your own set of parameters
I could not find any parameter file anywhere to empty. When I ran the second time I created a whole new directory structure from the first successful run.
Any help or understanding of how to fix this error?
