This project focuses on the problem of reconstructing 3D shapes from a single 2D image, utilizing a VAE-GAN model augmented with attention blocks. The model is trained on the ShapeNetCore dataset, which consists of over 48,600 3D models across 55 common categories. I have included a CVPR format latex-typed project description in this repository. View detailed project description here
