i have a photo and I want to obtain the coordinates in a table form of its edge so that I could input the data into Autodesk Inventor

May I know how I can do it

    $\begingroup$ The edges of the photo? They'd be {0,0}, {0,1}, {1,1}, {1,0} in ImageScaled values... Do you mean the outline of the shoe in the photo? $\endgroup$ – Quantum_Oli Feb 13 '16 at 16:22

I am not familiar with Autodesk Inventor but here are 2 ways to generate x,y coordinates from an edge detection of your image:

to extract a list of edge coordinates

edgeCoordinates = PixelValuePositions[
    EdgeDetect[Import["http://i.stack.imgur.com/bBKot.jpg"]], 1];

Graphics[Point[edgeCoordinates]]

enter image description here


you can also get points manually using:

Right Click Get Coordinates

enter image description here


when you have clicked the outline in orange dots,

copy and paste the coordinates into an empty cell as a list

enter image description here

    $\begingroup$ @ Dr.belisarius I wish they would let me know why? so I could fix, improve or delete my answer. Perhaps I am missing something trivial? $\endgroup$ – Conor Cosnett Feb 13 '16 at 19:33

    $\begingroup$ Didn't realize it was getting downvotes (I upvoted). It seems to be a reasonable answer so don't delete it. $\endgroup$ – Daniel Lichtblau Feb 13 '16 at 20:25
