One of the main focus areas for ballistic analysis is on the projectile(s) itself. While there are analytical codes for accurately predicting the flight path of a projectile, a new focus is on tracking the projectile. Animations like these show the developing capability for extracting data from high speed images, giving us opportunities to better control the pattern and flight path of projectiles.

Shotgun pattern with pellets identified. The labels around each pellet correspond to their locations in the picture and change from frame-to-frame.
Shotgun pellets can be tracked using some relatively simple algorithms built in MATLAB or similar software packages; in this example, the shot density (i.e. the number of pellets) is counted.
Corresponding pellet count shows the number of pellets within the red bounding box.
