comment Grid cuts my images
Removing ImageCrop works correctly... Strangely magnifying bigger than 1 also corrects it...

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.

you may also check 'ImagePartition'. i = Import["ExampleData/lena.tif"] ImagePartition[i, {45}] // Grid

comment Why is DiscretizeGraphics missing points on my curve?
Yes, I think here is a bug in DiscretizeGraphics algorithm skips the last segment.

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.

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.

comment How to patch fingerprint ridges
In literature I think it's called fingerprint ridges... In Mathematica docs you may search GradientOrientationFilter and example/VisualizeTheGradientDirection. Also the answer of @belisarius is forth for this Q might be helpful using hit and miss transform... mathematica.stackexchange.com/questions/19546/…

if you have mathematica 10.0. you may try RemoveBackground[img, {"Background", {LightYellow, 0.5}}]

comment How should I enter indexed terms? 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.

comment Managing Stack Exchange favorites via Documentation Center
@Kuba In an ideal situation, I would like to see this question favorited under documentation 'ref/Notebook' due to the keywords used. May be as a separate section simmilar to 'Detailed' section. However, as Timothy mentioned it may be very hard to edit Doc Center. But, may be it's easier to replicate the doc structure of Mathematica in an other gui or cell and associated and structure the favorites with this new gui.
