Strangely magnifying bigger than 1 also corrects it... Jan 21 comment Using 2 D FFT for filtering unwanted texture on an image did you see related question mathematica.stackexchange.com/questions/29265/… ? you can try data = InverseFourier[fdct]; Image[Chop@data] you need to chop it. the inverse Fourier may have imaginary parts.

Yes, I think here is a bug in DiscretizeGraphics algorithm skips the last segment. Dec 11 comment Why is DiscretizeGraphics missing points on my curve? For the first part you can use pts = {{.5, 0}, {1, 0}, {1, 1}, {.5, 1}, {0, 1}, {0, 0}}; Graphics@BSplineCurve[pts, SplineClosed -> True] so that you don,'t need to duplicate the first or last point. There is a bug I thing in DiscretizeGraphics. It forgets to ckeck if the shape is closed. And algorithm skips the last segment. Dec 9 comment Why is DiscretizeGraphics missing points on my curve? I don't now the exact answer but my guess is the problem is with line and BSplineCurve combination. The line is bounded piece wise linear primitive and BSplineCurve is a nonlinear primitive with an only approximation represented. If you try BoundaryDiscretizeGraphics you get an error saying 'BoundaryMeshRegion::buncl: At least one boundary was not closed in'. So the line and spline joined points does not overlap due to approximation of spline.

For example, constants $n_k$ for $k\in\{1,\,\ldots,\,N\}$ Could you mind explaining the new functionality Indexed a bit more in details. What does it return just formatted text ... Can we assign values to Indexed what is the difference between part and Indexed etc. It will be very helpful for future users.
