How can I display/detect object using different oriented rectangle according to the image orientation? As for example......

But it looks like you're already using capabilities of the Computer Vision System Toolbox. Do you already have the coordinates of the green rectangles and you just need to straighten them, then extract and show the aligned image?

To draw tilted rectangles, I think you need to use plot() rather than rectangle().

I also want to know how to rotate the surrounding bounding box with the same angle as the object orientation, if the bounding box is used with regionprops function in MATLAB....?

Hello Sir, Thank you for your support. But I have not try the Hu's moments yet, I have to first understand it properly. Then, I will implement it.
I have not any specific image taken by camera. I just working on Image having different standard shapes (like square, Hexagon, rectangle with any orientation).
Thank you.

If you want to determine what shape it is, then you can just find the centroid, find the boundaries, find the distances from the centroid to the boundary points, and then look for peaks in the distance array. I'm attaching a demo.
