距离变换的主要目的是通过识别目标点和背景点,将二值图像转换为灰度图像。 距离变换主要分为欧氏距离变换和非欧氏距离变换。 非欧距离变换包括棋盘距离变换、城市街区距离变换和倒角距离变换。 棋盘距离:| x1 - x2 | + | y1 - y2 | 城市街区距离:max( | x1 - x2 |, | y1 - y2 | ) ...
Pytorch Chamfer Distance. Include aCUDAversion, and aPYTHONversion with pytorch standard operations. NB : In this depo, dist1 and dist2 are squared pointcloud euclidean distances, so you should adapt thresholds accordingly. F - Score CUDA VERSION ...

A simple example Pytorch module to compute Chamfer distance between two pointclouds. Installation You can install the package using pip. pip install chamferdist Building from source In your favourite python/conda virtual environment, execute the following commands. NOTE: This assumes you have PyTorch...
This is an installable implementation of the Chamfer Distance as a module for pyTorch fromChristian Diller. 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 show...
