Abstract
A fuel filter inspection method includes capturing an image of a fuel filter sample using an imaging device and sending the captured image to an image processor. The method further includes the image processor receiving the captured image, thresholding the captured image to generate a binary image, determining sizes for a plurality of particles present in the binary image, comparing the size of each of particle of the plurality of particles to a particle size threshold, and quantifying the number of particles of the plurality of plurality of particles with a size greater than the particle size threshold. The method further includes the image processor comparing the number of particles of the plurality of particles with a size greater than the particle size threshold to a particle count threshold, and modifying a graphical user interface to indicate a state of the fuel filter sample based on the comparison.
