 Jan21 comment How can I train a binary classifier to find a logo? @M.R did you check the link its explained step by step in the 2. Answer. There's also other related links there. Dont expect 90 persent accuracy. 80 isreasonable result. Jan21 comment How can I train a binary classifier to find a logo? You may check this answer. Mainly, you may create codebook+histogram explained in stackoverflow.com/questions/19048891/… Also, you may use ImageKeypoints with option "Descriptor" with surf descriptor instead of sift. Dec17 comment How can I transfer colors from first image into second image? you may check HistogramTransform and MatchImageHistograms. Nov12 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"] Nov7 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 Nov2 comment Get 2d corner coordinates / layout using edge detection you should see the post mathematica.stackexchange.com/questions/19546/… Oct9 comment How to generate random points in a region? @ybeltukov Very nice answer. Could you just explain briefly why you use DirichletDistribution? Oct9 comment Converting image data to array Might be useful topic 'Detecting grid lines in a raster image' mathematica.stackexchange.com/questions/13918/… Sep16 comment How to call a java method that takes a boolean (not Boolean)? You may try tocall Boolean.TRUE Sep9 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. Sep9 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]; Aug28 comment Pass the list of variables into function to change their values you may check this question and answers mathematica.stackexchange.com/questions/22376/… Aug27 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. Aug25 comment Grid rows height & SpanFromAbove issue Is there any particular reason you didn't put "m" in the first one and what is the expected result? Aug25 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/… Aug19 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}]] Jul23 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. Jun11 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] May17 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. Apr28 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 :) ).
