comment Identifying critical points of 2/3D image/cubes
@chris en.wikipedia.org/wiki/Marching_cubes is 3D, based on en.wikipedia.org/wiki/Marching_squares mentioned there. Also Azim's answer there is interesting to read. PS: Under wikipedia matlab or java codes are also available.

@chris Did you see stackoverflow.com/questions/263305/drawing-a-topographical-map it might be helpful.

comment Estimate parameters of the state space model
I don't think there is single command to handle this in Mathematica. You have to use FindMinimum or FindFit command and define your own criteria to fit the data you have. The criteria should include the difference between your data and the model output by calculating the norm which you should minimize.

comment Circle detection using invariance kernels
@rcollyer yes you are right. Before the edited version you can. But the final version might change alot and you cant cite it.

@Szabolcs even the authors can't distribute on their own site. They transfer the publishing copyright to publisher. I think we are all unhappy except publishers. ..

You can not distribute the paper however you can cite and put the relevant part.

@user2667048 you can try imp = Import["A.mat", "LabeledData"]; AA = "A" /. imp ; BB = "B" /. imp ; x = LinearProgramming[{0, 0, -1}, AA, Flatten@BB, {{-1, 100}, {0, 100}, {0, 100}}];

comment Signal processing by means of WaveletTransform
@Sektor I think you are right as explained in the link. It may also depend on the basis function. The main problem is Mathematica does not have a function such as scale2frequency as in matlab. It may be interesting to see the complete code for future use of the forum when you have time. see the link in dsp I think OP needs similar approach in Mathematica dsp.stackexchange.com/questions/10127/…

@andy you may try 'Show[image, Graphics[{Red, Text[#1, Flatten@#2] & @@@ cenData}]]' and check mathematica.stackexchange.com/questions/18393/… for more info

comment Gram Schmidt Process for functions
@D.N.S you can try rr[x_, y_] := Piecewise[{{ff[x, y], y <= x}, {gg[x, y], x > y}}]; Orthogonalize[{{1, 1}}, rr, Method -> "GramSchmidt"]
