Validation:Algorithms

External Validation

Correctly implementing algorithms and producing the expected performance can be non-trivial. Academic papers more of then than not leave out important implementation details which are needed for reproducing their results. BoofCV contains over a thousand internal tests to help ensure correctness of its algorithms, but testing against external sources is often required to catch more subtle bugs. This page contains a list of important algorithms inside of BoofCV and if they have been validated against external libraries or not. Just because some code has not been validated does not mean it is incorrect.

Status	Meaning
Validated	As good or better than original code or test data
Needs Work	Producing results which are not as good as expected
NA	Significantly different from original. See comments in code
	Blank means that it has not been externally validated
