Implement the binary region moment features pro$-$ posed by Hu $($Eqn$.(10\mathrm{.}47))$ and verify that they are invariant under image scaling and rotation. Use the test image in Fig. $10\mathrm{.}2521($or create your own$),$ which contains rotated and mirrored instances of the reference shapes, in addition to other $($unknown$)$ shapes.
