Chamfer Distance for pyTorch This is an implementation of the Chamfer Distance as a module for pyTorch. It is written as a custom C++/CUDA extension. As it is using pyTorch'sJIT compilation, there are no additional prerequisite steps that have to be taken. Simply import the module as shown...
目前要做两个无序点集之间的相似性计算,在看过Chamfer Distance后,个人觉得CD的计算方式决定了其无法处理两个点集整体分布差异大,但是局部有部分点距离很近的情况,而这种情况在点集中是一定可能出现的,因此使用EMD可以保证每个点集都有一一对应的整体cost最小点 Earth Mover Distance 在网上有很多EMD的解析和案例分析,...
# We compare the two sets of pointclouds by computing (a) the chamfer loss loss_chamfer, _ = chamfer_distance(sample_trg, sample_src) # and (b) the edge length of the predicted mesh loss_edge = mesh_edge_loss(new_src_mesh) # mesh normal consistency loss_normal = mesh_normal_consist...
chamfer_distance, the distance between the predicted (deformed) and target mesh, defined as the chamfer distance between the set of pointclouds resulting from differentiably sampling points from their surfaces. However, solely minimizing the chamfer distance between the predicted and the target mesh ...
