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];
Mathematica 9.0 (best result)
Mathematica 10.4 (discontinuities exist)
Mathematica 11.2 (disconnected lines are visible)
Obviously I know how to get results like that of version 9.0 in 11.2. But my question is simple: Why do some of the Mathematica functions with default options behave differently between newer and older versions ?
I am quite annoyed at WRI for these odd behaviours !
