I have often noticed that examples of the past when done in newer versions of Mathematica generate inconsistent results. A prime example related to the following post (Character edge finding):
pic = Thinning@Binarize[GradientFilter[Rasterize[Style["\[Euro]",
FontFamily -> "Times"], ImageSize -> 200] // Image, 1]];
pdata = Position[ImageData[pic], 1];
lcp = ListCurvePathPlot[pdata];
This simple piece of code gives different results in Mathematica 9.0, 10.4 and 11.2 with default options. I have posted the results on StackExchange
(click the [link][1] to see).
Note: this is not the only example where I have seen differences.
**To the WRI quality assurance department**:
Can you kindly check why similar functions do not behave the same across different versions ?? I think it is more crucial to establish whether
the built-in functions are working properly rather than releasing more and more functions without appropriate checks.
