 Iterative Closest Point (ICP) coregistration is an iterative point cloud registration method from [Besl and McKay (1992)](https://doi.org/10.1117/12.57955). It aims at iteratively minimizing the distance between closest neighbours by applying sequential rigid transformations. If DEMs are used as inputs, they are converted to point clouds.
 As for Nuth and Kääb (2011), the iteration stops if it reaches the maximum number of iteration limit or if the iterative transformation amplitude falls below a specified tolerance.
 
-ICP is currently based on [OpenCV's implementation](https://docs.opencv.org/4.x/dc/d9b/classcv_1_1ppf__match__3d_1_1ICP.html) (an optional dependency), which includes outlier removal arguments. This may improve results significantly on outlier-prone data, but care should still be taken, as the risk of landing in [local minima](https://en.wikipedia.org/wiki/Maxima_and_minima) increases.
