Chamfer distance loss. Parameters Chamfer distance (CD) is a popular metric and training loss to measure the distances between point clouds, but also well known to be sensitive to outliers. The per-point Cham-fer gradient creates a many-to-one collapse that is the unique attractor of the forward term and cannot be resolved Feb 24, 2023 · The chamfer distance loss encourages the generated point cloud to be as close as possible to the target point cloud. We use the unsquared Euclidean variant, which computes average nearest-neighbor distances in both directions. Chamfer distance (CD) is a popular metric and training loss to measure the distances between point clouds, but also well known to be sensitive to out-liers. Feb 24, 2023 · The chamfer distance loss encourages the generated point cloud to be as close as possible to the target point cloud. g. It is written as a custom C++/CUDA extension. The per-point Chamfer gradient creates a many-to-one collapse that is the unique attractor of the forward term and cannot be resolved by 4 days ago · All models are trained using the AdamW optimizer to minimize a Chamfer distance loss between predicted and ground-truth emitter sets (Fan et al. loss Loss functions for meshes and point clouds.
