A pair of the proposed U-Nets with a loss function based on the structural similarity index measure can be applied to synthesize sparse-view sampling sinograms and denoise reconstructed images. The experimental results indicate the performance of the proposed method is superior to those of other U...

In the medical CT fi eld, sparse-view sampling has prac-tical implications in reducing ionizing radiation, which is harmful to people’s health, decreasing the scanning time and improving the scanning limits in many scenarios [2, 3]. In the industrial CT, when it was limited by scanning ...
InstantSplat: Sparse-view SfM-free Gaussian Splatting in Seconds This repository is the official implementation of InstantSplat, an sparse-view, SfM-free framework for large-scale scene reconstruction method using Gaussian Splatting. InstantSplat supports 3D-GS, 2D-GS, and Mip-Splatting. Table...

5.1Sparse-View Reconstruction We first validate our choice of SART as the solver for the data term in Eq. (1). We run experiments comparing SART head-to-head with Conjugate Gradient (CG) in a sparse-view setting, using the TV regularizer in both cases. In particular, we show the reconst...
their performance notably declines in scenarios with sparse views. In response to this challenge, we introduce WSCLoc, a system capable of being customized to various deep learning-based relocalization models to enhance their performance under weakly-supervised and sparse view conditions. This is realiz...
Creating 3D assets from single-view images is a complex task that demands a deep understanding of the world. Recently, feed-forward 3D generative models have made significant progress by training large reconstruction models on extensive 3D datasets, with triplanes being the preferred 3D geometry ...
