# Classify Moving Objects
Moving objects, such as pedestrians or moving vehicles, will not appear in the same position in different intervals, thus the **Classify Moving Objects** filter can be used to classify such noise.
The moving object filter checks whether points have neighbors from different intervals within a given **Search Radius**. Alternatively, you can check that the points have neighbors from a different time (**Mode->Time Difference**) within a given **Search Radius**.
In the example below, points that do not have a neighbor from at least 1 different interval within a 0.10 m 3D radius will be classified as noise:

# Agent Instructions: Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter:
```
GET https://docs.phoenixlidar.com/spatialexplorer-8-and-9/user-interface/toolbars/analytics/classify/classify-moving-objects.md?ask=
```
The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
