High-Quality Reconstruction of Depth Maps From Graph-Based Non-Uniform Sampling

Depth sensing is essential for intelligent computer vision applications, but it often suffers from low range precision and spatial resolution. To address this problem, we propose a novel framework that combines non-uniform sampling and reconstruction based ...
