Frequently Asked Questions

  1. Is BoofCV Thread Safe?

Unless a class explicitly states that it is thread safe you should assume that it is not. In practice, if you are calling a static function in a Util* or *Ops class there is a good chance that it is thread safe. Classes tend to recycle data structures each time they are invoked and are extremely not thread safe. For example, if a feature detector returned a Point2D_F32 with the feature's location then it owns that data structure and will reuse it the next time its invoked. If you need to save the value of a returned data structure make a copy of it. To get around this issue each thread should have its own instance of a class.

  1. How do I donate code

Post a message on the message board about the code you wish to donate and someone will contact you. Before you donate code make sure you actually own it. If you work for a company check with the legal department since they probably own it even if you did it in your spare time. All donated code will need to be assigned over to BoofCV and released under an Apache 2.0 license.

The main reason for the copyright being assigned is so that if the license needs to be changed in the future that can be done without getting permission from a few hundred people who donated code over the years. Other open source projects have been stuck because of this issue. Your donation/contribution will always be achknowledged in the code's comments. In the future there might be an extras package for code which is not owned by BoofCV.
