Could someone kindly guide me as to how to get all the image processing functions (segmentation, analysis, morphological operations etc... ) for 2D and 3D images in Mathematica including ones that do not begin with word "Image"

  • $\begingroup$ i am aware of that. I was thinking if there is a way to get a list of functions within the notebook. $\endgroup$

    $\begingroup$ WolframLanguageData[EntityClass["WolframLanguageSymbol", {"FunctionalityArea", "ImageSymbols"}]] gives a partial list. $\endgroup$

    $\begingroup$ @J.M. that should be one answer. It gives a longer list than the current answer, but doesn't include {BilateralFilter, ColorConvert, ColorQuantize, ColorReplace, EntropyFilter, ExampleData, GaussianFilter, GradientFilter, HistogramTransform, ImageHistogram, ImageIdentify, ImageInstanceQ, Import, MeanShiftFilter, Rasterize, TotalVariationFilter}, as these are considered "ColorSymbols", "FileSystemSymbols", "GraphicsSymbols", "HistogramSymbols", "ImageFilterSymbols", "MachineLearningSymbols", or "PacletSymbols" $\endgroup$

    $\begingroup$ @J.M. That's not a complete list, but just the complement of your list with Bob's. Not going to answer, as I already closed that nb without saving. Moreover Entitys are annoying and annoyingly slow. $\endgroup$

EDIT: Added Union to sort and eliminate duplicates. Displayed results as table with Grid

base = "https://reference.wolfram.com/language";

len = StringLength[base <> "/ref/"];

funcs = StringTake[#, {len + 1 ;; -6}] & /@
       Select[
        Import[
         base <> "/guide/ImageProcessing.html",
         "Hyperlinks"],
        StringTake[#, len] === base <> "/ref/" &] //
      Flatten // 
     ToExpression // Union // Quiet;

funcs // Partition[#, 20] & //
  Transpose // Grid[#, Alignment -> Left] &

enter image description here

Or more simply (provided by Karsten 7.)

Multicolumn[funcs, 3]

EDIT 2: For a more complete listing, scrape multiple guides related to image processing

guides = {
   "ImageProcessing",
   "BasicImageManipulation",
   "ImageFilteringAndNeighborhoodProcessing",
   "SegmentationAnalysis",
   "ImageRestoration",
   "ImageGeometry",
   "MathematicalMorphology",
   "ComputerVision",
   "3DImages",
   "RasterImageFormats",
   "ColorProcessing"
   };

guideHyperlinks =
  "http://reference.wolfram.com/" <>
     "language/guide/" <>
     # <> 
     ".html" & /@ guides;

base =
  "http://reference.wolfram.com/language/ref/";

hyperlinks = Select[
    Flatten[
      Import[#, "Hyperlinks"] & /@
       guideHyperlinks] //
     Union,
    StringTake[#,
       StringLength[base]] == base &] //
   Quiet;

funcs =
  StringTake[#, {StringLength[base] + 1, -6}] & /@
   hyperlinks;

Length[funcs]

(*  254  *)

Multicolumn[funcs, 3]

(* large output deleted *)

    $\begingroup$ Multicolumn is quite convenient here: Multicolumn[funcs, 3] $\endgroup$

This will give all of what you want

CanonicalName@*EntityList@
 Entity["WolframLanguageSymbol", {"FunctionalityAreas" -> 
    "ColorSymbols" | "ImageFilterSymbols" | "ImageSymbols"}]

{AlphaChannel,BarcodeImage,<<262>>,ZoomFactor,$ImageFormattingWidth}

  • $\begingroup$ I don't think that WordCloud, VectorColorFunction, ChromaticityPlot, ZoomCenter and some other returned symbols should be considered as image-processing functions even in an extended sense. I also don't think that such symbols as White, Hue etc. should be included: they are related to image-processing functionality but all the language basics are related to this functionality in some sense (for example, Blank, Pattern, Rule etc.)! There is no point to include everything related into a list of image-processing functions. $\endgroup$
