Could anybody recommend a good, "playable" example that demonstrates how to use opencv_createsamples and opencv_traincascade for image detection? I tried to follow Cascade Classifier Training with my own images and it didn't work well.

There are multiple tutorials out there on how to create your own cascade classifier, however, finetuning the parameters is always the hard part of the job. Keep in mind that many guides out there use the older cvHaartraining, but these guides use the same background. However, try to stick to the newer cascade classifier in C++ which is way better developped. You just have to look in docs to look for corresponding C++ functionality.

Some links that are interested and used frequently by forum users:

Yeah.. I think that is the problem. There are many tutorials, many (maybe all) have outdated documentation, or work off of datasets that aren't provided.

None are "playable".

And the tools seem to simply crash when it doesn't like your parameters. So, you quickly hit a brick wall.

I think that if you stick to this forum and search for cascade classifier training that you will hit more then enough information to solve your problems. Last year this topic has popped up multiple times with quite some good information about all the parameters contained.
