I'm thinking about a something for a long time:
If I have a vectorised simple picture
,can I easily make a parametric plot to discribe this picture:
I know that I can use fourier transform to decompose and transform the vectorised picture into fourier series but the main problem is that to do that I have to have an initial function that describe the x and y coordonates of the image during the time. I could use a polynomial interpolation but it's unrealable and that became worse and worse if I add more points because of runge's phenomenom and that function would be too round and smooth to be used

Do anyone have an idea?
