Abstract
Methods and systems for filtered image data recovery using lookback include storing first, second, and third data captures received from the image sensor in a first memory component and a second memory component. The methods and systems also include identifying a second detection in the second data capture and a third detection in the third data capture by filtering the first, second, and third data captures. The second detection and the third detection each exceed a pixel intensity threshold. The methods and systems also include correlating the second detection and the third detection to identify at least one track. The methods and systems also include detecting a first detection in the first data capture stored in the second memory component, the first detection being a pixel intensity value that is less than the threshold or an initiation event having a pixel intensity value that is less than the threshold.
