Revision history [back]

For the creating of a cascade classifier you should read up on

1. The principle
2. The training interface
3. The example detection software

All the software is found in the application folder. There you have annotation, sample creation and training software.

Updating an existing model is not possible in OpenCV. It will require you to re-engineer the training software to pick an already trained model and continue on that. Also multiple angles will be a problem for the cascade classification since it is NOT rotation invariant.
