For example:
`TestUS4DCylAxialPlanarFigureMaskStatistics_time1`
|MITK Version| Entropy | Kurtosis | MPP | max | mean
|----------| -------- | ------ | ------|----|---
|2016.11 GUI|6.1778|1.587|115.45|199|115.45
|2018.04 GUI|6.1778|1.587|115.45|199|115.45
|Test (since f94aca1d1637, 2 years ago)| 6.218151288002292|1.7322676370242023|121.11663807890223|199|121.11663807890223
So, obviously, there's some difference between the GUI and the direct usage of `ImageStatisticsCalculator` (even with the same data)
Also, the tests seem to be fine:
`OK (33 tests)` in `LastTest.log`
However, there are 34 teststing statements that are not fine (also in `LastTest.log`):
```
Calculated mean grayvalue '-21474836.48' is equal to the desired value '128.00' [FAILED]
In D:\dev\MITK\master\Modules\ImageStatistics\Testing\mitkImageStatisticsCalculatorTest.cpp, line 1674: calculatedMean == testMean : [FAILED]
