Final image does not respect edge boundaries

[ParkerEwen5441]

When running the script as described in the ReadMe, the final image generated in the build folder appears to be a random collection of convex polygons which do not respect the edges of the objects in the image. This may be caused by an update to CGAL?

Hi, when I run the code like 3 years ago on the same image, I got result like this.

Which version of CGAL and OpenCV are you using?

[yimengli46]

Just checked it on my old machine.
I used CGAL-4.10 and OpenCV 2.4.10

Hi Yimeng, I have tried updating your convex superpixelization code to CGAL 5.2 and OpenCV 4.5.1, but so far have been unable to do so. The outputs with these versions of the libraries still returns images which do not match up to the ones you show in your repo. Cheers, Parker

Hi Parker,

The code outputs should match exactly with the visualizations.
Because this is a course project code. I just put the code and results directly on github.

Let me know if I can do something to help you.
Can you save the intermediate results like the line segment detection?
I can also share the intermediate results I had.

Thanks,
Yimeng

Hi Yimeng, I am also running the code directly after compiling, so I am not sure what the issue could be. Ive included the intermediate images I am getting in the zip file. Maybe it is the newer version of CGAL or OpenCV? I am using CGAL-5.2 and OpenCV-4.5.1. I really appreciate your help! Cheers, Parker

I didn't see the zip file in the email.

[ParkerEwen5441]

I have attached the pictures directly. [image: img1.png][image: img2.png][image: img3.png][image: img4.png][image: img5.png][image: img6.png][image: img8.png][image: vd_img1.png][image: vd_img2.png][image: vd_img3.png][image: vd_img4.png][image: vd_img10.png][image: vd_img11.png]

Still cannot see the images.
