| Summary | 0010442: itkRandomNonRepeatingIteratorWithIndex has non-reproductible behavior |
| Description | Using ReinitializeSeed to control the seed of the random number generator, i can't have a reproducible behavior.
What I expect is that iterating on two images of the same size with the same initial seed means walking through the same set of pixels in the same order.
|
| Steps To Reproduce | |
| Additional Information | A program to reproduce the bug is attached.
And here is a fix :
in itkImageRandomNonRepeatingConstIteratorWithIndex.h, replace the implementation of RandomPermutation::ReinitializeSeed(int seed) from "m_Generator->Initialize ( seed );" to "m_Generator->SetSeed( seed );"
