# How can I generate coordinates (points) of equal distance from each other along a given path (e.g a black line in an image)

I need to be able to obtain X and Y coordinated of a path, from an image, shape, and userdrawn paths.

If possible, I would like to do the same in 3D, obtaining the Z axis as well.

Any suggestions? I have tried to use matlab for this, but I am stuck, any help is greatly appreciated.

Below is an example of points that trace the following image: I would like to be able to generate similar points, but for any image/path.

there are 5000 points, this only some of them..
