How to re-train the classifiers for opencv_contrib text module

edit

Thank you. I believe I came across that, however, it provides no instructions and the README is not that much of a help either. Thats why I was looking for some help on how to get started with it

it should work somehow like this:

cd erfilter_train-master
# this should generate a makefile:
cmake .

# this should build 4 progs, extract_featuresNM1,extract_featuresNM2, train_featuresNM1, train_featuresNM2
make

# build datasets:
python build_csv_datasetNM1.py
python build_csv_datasetNM1.py

# finally, train classifiers:
./train_classifierNM1
./train_classifierNM2

UPDATE:

i tried my own dogfood, and encountered a problem, (opencv ml code changed), see https://github.com/lluisgomez/erfilte..., i guess, you will need to get my pr branch there (or apply fixes manually.

GOOD LUCK !

Thanks, I see the PR. I'll try it out. Thanks!
