SIMPC: Learning Self-Induced Mirror-Point Consistency for Unsupervised Point Cloud Denoising
Chengwei Zhang, Xueyi Zhang, Tao Jiang +4
In point clouds, noise directly perturbs point coordinates that encode both spatial location and geometry, making one-to-one correspondence construction more challenging than in im…
Variational Diffusion Channel Decoder
Chengwei Zhang, Yifan Du, Siyu Liao
Neural channel decoder, as a data-driven channel decoding strategy, has shown very promising improvement on error-correcting capability over the classical methods. However, the suc…
Beyond Geometry: Efficient Topologically-Grounded Navigation in Complex 3D Environments
Yifan Du, Chengwei Zhang, Siyu Liao +1
Ground robot navigation in complex 3D environments is often hindered by geometric ambiguity, where non-traversable structures such as furniture share local geometric properties wit…
Deep Learning For Point Cloud Denoising: A Survey
Chengwei Zhang, Xueyi Zhang, Mingrui Lao +5
Real-world environment-derived point clouds invariably exhibit noise across varying modalities and intensities. Hence, point cloud denoising (PCD) is essential as a preprocessing s…
