# Classify Noise

**Classify Noise** is an isolated point filter. This means that any points without a sufficient number of neighbors (**Neighbor Count**) within a given distance (**Search Radius**) will be assigned to the **Output Class**, in this case the Low Point (noise) class. This is ideal for classifying sparse noise points that occur mid-air or far below ground. 

In the example below, all point classes are analyzed and any points without at least 10 neighbors within 1 m (3D distance) will be assigned to the Low Point (noise) class:
