Methods and apparatus to track and classify objects

A non-transitory machine readable storage medium comprising instructions to cause programmable circuitry to at least:

• pre-process an image to identify potential targets;
• filter, based on the identified potential targets, at least one of the images to determine a presence of a persistent object therein;
• characterize a looming characteristic of the persistent object, the looming characteristic corresponding to the persistent object maintaining a relatively constant bearing;
• and
• classify the persistent object as point-like based on the looming characteristic meeting or exceeding a looming characteristic threshold.

A method comprising:

• pre-processing, by executing instructions with processor circuitry, an image to identify potential targets;
• filtering, by executing instructions with the processor circuitry, at least one of the images based on the identified potential targets to determine a presence of a persistent object therein;
• characterizing, by executing instructions with the processor circuitry, a looming characteristic of the persistent object, the looming characteristic corresponding to the persistent object maintaining a relatively constant bearing;
• and
• classifying, by executing instructions with the processor circuitry, the persistent object as point-like based on the looming characteristic meeting or exceeding a looming characteristic threshold.
