Below is a scatter plot from array that I get using boundary(). How can I get a region so that I can use regionprops() to find the centroid, orientation etc.

You could dilate the image repeatedly until the boundary closed (at which point there would be only one blob) and then erode it again maintaining continuity; see bwmorph() for useful functions.
