@Deniel,
There is something wrong with the article of CSF in several links, such as author and year.
https://github.com/CloudCompare/CloudCompare/releases
https://github.com/CloudCompare/CloudCo ... ANGELOG.md
https://github.com/CloudCompare/CloudCo ... 424f31ea44
It should be:
Zhang W, Qi J, Wan P, Wang H, Xie D, Wang X, Yan G. An Easy-to-Use Airborne LiDAR Data Filtering Method Based on Cloth Simulation. Remote Sensing. 2016; 8(6):501.
Please correct it. Thank you.

Ok that's fixed (but the last one which reflects the commit at the state it was done at that time and it cannot be changed).

Hi, Daniel. Thank you for the corrections.
By the way, we are pleased to announce that CSF can be used in Python environment now. More details can be found here,

Investigating the performances of commercial and non-commercial software for ground filtering of UAV-based point clouds
In the above paper, CSF was compared with the ground filtering algorithms of several softwares including Photoscan and Global Mapper. In the paper, they reported:
The results showed that the CSF algorithm presented the best filtering results for both test sites with Total Errors of 6% and 4.5% in the sites 1 and 2, respectively.
Performance analyses revealed that the recently introduced CSF algorithm yielded the minimum Total Errors in both test sites (see Table 4).
it was easier to find the optimum parameters for the CSF.
The main advantage of this algorithm is that it uses very few easy-to-set parameters.
Considering the performance and time efficiency, the freely available CSF algorithm as found to be the optimum ground filtering algorithm for UAV-based point clouds.

CSF is integrated in commercial photogrammetry software - 3DF Zephyr
https://www.3dflow.net/
3DF Zephyr is a photogrammetry software, like photoscan and visalsfm. It is fast and easy-to-use.
3DF Zephyr Free can process 50 photos.
Now CSF is integrated in the newest version 4.0. You can find it in two ways. When you export DTM or select point clouds by choosing method of Cloth Simulation. Enjoy it.

Please! the plugin is not more disponible in Cloude Compare? It is not active in version 2.9.1. It is only in list but no way to active then.

Have you selected/highlighted a cloud (and not the container by the way)?

Sorry, I did not that. The filter is now fine. Thanks.
