title: Binary images into polygons
body: <p>How do I transform a binary image with one single mask in it (whose values are one) into a polygon in PYTHON? My goal is to calculate the inner-angles of this mask and the orientation of the countor-lines. I assume I have to transform the mask into a polygon before I can use other libraries that do these calculations for me. I rather not use Open Cv to tdo this transformation since I have faced problems installing it in a Windows 64/Spyder envronment. Thanks for any help!</p>
