3D Hole Filling using Deep Learning Inpainting

The current work presents a novel methodology for completing 3D surfaces produced from 3D digitization technologies in places where there is a scarcity of meaningful geometric data. Incomplete or missing data in these three-dimensional (3D) models can lead to erroneous or flawed renderings, limiting their usefulness in a variety of applications such as visualization, geometric computation, and 3D printing. Conventional surface estimation approaches often produce implausible results, especially when dealing with complex surfaces. To address this issue, we propose a technique that incorporates neural network-based 2D inpainting to effectively reconstruct 3D surfaces. Our customized neural networks were trained on a dataset containing over 1 million curvature images. These images show the curvature of vertices as planar representations in 2D. Furthermore, we used a coarse-to-fine surface deformation technique to improve the accuracy of the reconstructed pictures and assure surface adaptability. This strategy enables the system to learn and generalize patterns from input data, resulting in the development of precise and comprehensive three-dimensional surfaces. Our methodology excels in the shape completion process, effectively filling complex holes in three-dimensional surfaces with a remarkable level of realism and precision.
