ASCII radar data normalizer to find specific objects in it (called invaders). All input data is stored in ./data directory.
bin/exec
Will print out result with founded invaders with match score (only which is included by TOLLERANCE). Also, it will print out clean, normalized radar with founded objects.
In lib/radar_processing.rb RADAR_INPUT_LOCATION and INVADERS_INPUT_LOCATION can
be changed to different locations. TOLLERANCE should be adjusted as well for new data (most likely it would be between 0.1 for good signal data and 0.3 for very bad signal data). With bigger tollerance value it is more likely to get false positives.
Very naive approch reasonable space complexity and brute force matching. Algorithm allow to find objects which is partly visible in radar (no less than 70%).
