How do I create a polygon from a set of interest points?

I wish to create a boundary, of the region of interest, with a set of corner points obtained after using minimum Eigen value algorithm and the detectMinEigenfeatures command and have selected 50 strongest corner points. I don't quit

e know how to do it. Can someone help me out with the code?

As you can see from the image, I wish to plot the boundary of the the region, removing interest points outside the brightest region.

I've tried it already and it hasn't yielded a proper boundary. I've tried using "boundary" as well, and so far it's given me the best results but I want them to be even more along the lines of the region

I've achieved the shape I've wanted using boundary function. Thanks anyway!
