Regression testing is defined as the retesting of a software system that has been modified to ensure that any bugs have been fixed and that no other previously-working functions have failed as a result of the changes and that newly added features have not created problems with previous versions of the software. Regression testing is initiated after a programmer has attempted to fix a recognized problem or has added source code to a program that may have inadvertently introduced errors. We describe a framework for automated regression testing and reporting of test results for image processing algorithms by comparing their output data with previously generated or gold standard data.
