I was doing an internship and designing algorithms reverse engineering the 3D model of the object with point clouds. The scanning was a debug test and my face looks like snapped by Thanos.
When I was an undergraduate, I wrote a CV algorithm with C++ and OpenCV that converts images to "string threads". It did not work everytime, but this was the most successful one from the photo of my pal Ziqi Gao (HKUST).
