Ping-Ping Filter
Description
The filter has three different strengths. As the
ping-to-ping filter compares the echoes from the last
ES70, it will take this selected amounts of transmissions
("pings") to make a stable presentation when changing
most of the ES70 parameters. The filtering routine
takes the vessel's movements into consideration when
comparing the echoes from ping to ping. The filter
works by comparing each separate pixel colour from the
previous pings.
