Foreign object debris (FOD) detection is an important term in the field of aviation as small sized. FOD can cause pecuniary as well as life forfeiture. Many FOD detection systems have been instigated for circumventing this menace. This paper is presenting a novel enactment of maximally stable extremal regions (MSER) detector for detecting FOD on aircraft operating surfaces. Detail analysis revealed that MSER was able to detect FODs of very small sizes like 0.6 inch × 0.6 inch with repeatability accuracy of 92%.
