LIDAR Sensor Scan Filters

This program reduces noise in the data coming from a LIDAR sensor attached to a robot. It filters the scans into a Range and a Temporal Median filter.

Example

Here is an example of scans of size 20:

Give the value for T (Times updated, less than 6): 
4
The length of each Scan:
