comment How can I transfer colors from first image into second image?
you may check HistogramTransform and MatchImageHistograms.

comment Is there a way to show some “weighted” residuals after LinearModelFit?
you may try Rescale. something like: data = {{0, 1}, {1, 0.05}, {3, 2}, {5, 4}}; dat=Rescale[data, {-0.5, 0.5}] lm = LinearModelFit[dat, x, x]; lm["FitResiduals"]

comment Distance between vectors does not match distance between probability distribution
I think Euclidean distance is not right measure for distributions. you may check en.wikipedia.org/wiki/Statistical_distance

@ybeltukov Very nice answer. Could you just explain briefly why you use DirichletDistribution?

comment Calculating a potential function using the finite element method
@MarkMcClure yes you are right. It is also mentioned in other discussions that some parameters are ignored. However, by discretizing region as in Q 3 {0, 0} problem disappears.

comment Calculating a potential function using the finite element method
problem 2 and 3 can be corrected by using DiscretizeRegion. dis = DiscretizeRegion[reg] and than mesh = ToElementMesh[dis, MaxCellMeasure -> 0.0005, "MaxBoundaryCellMeasure" -> 0.01];

comment Object separation from a 2.5D surface
@zeckra Instead of dealing with geometric models how about defining problem as optimization task and fitting biggest blob or sphere? If I am not mistaken MichaelE2 has related nice solution for 2d circle.

Is there any particular reason you didn't put "m" in the first one and what is the expected result?

comment Proving (self) similarity with Mathematica - Reccurrence Plots, Similarity Plots etc
May be you can use fractal dimensions to measure the similarities. Also related post might help 'Measuring fractal dimension of natural objects from digital images' but mainly for images mathematica.stackexchange.com/questions/13125/…

comment Strange behavior of `BoundaryMeshRegion`
I also think it a bug. An easy way to achieve the same result is with r = BoundaryDiscretizeRegion[Cuboid[{4, 4, 4}, {6, 6, 6}]]

comment Is there a list of Octave functions mapped to the related Mathematica one?
@Mr.Wizard Programming wise yes there are many flexibilities in Mathematica and hard to map one by one. However, toolboxes such as image possessing, statistics, wavelets, ect. has very similar commands. It may need a lot of effort to map, but as community page one can improve and add thing as common effort. I personally think it will be quite beneficial for future 2 program users.

comment How to control the layering of graphics displayed with Show
you may use Overlay and SetAlphaChannel Overlay[{isosurface, SetAlphaChannel[ Graphics3D[{Black, PointSize[0.05], Point[geom]}, Boxed -> False], .5]}, All, 2]

comment How to count the number of n-gons and line intersections in an image of a complete graph?
@GenericUsrnme Do you want image processing solution or graph based solution with Mathematica. you may check mathematica.stackexchange.com/questions/19546/… belisarius's solution for detecting intersection point using image processing solution. For 2d intersection detection algorithms you can check mathematica.stackexchange.com/questions/24211/… for references form this site.

comment Generating x,y coordinates for an edge detection
@nikie Overall, nice approach, but I think you need to clean shadows on the left hand side of the image to get it right size (min max includes the shadow :) ).

nice to see use of CurvatureFlowFilter.
