The apparatus/method includes steps of receiving a clean image of a vehicle interior and a second image of the vehicle interior after a passenger has occupied the vehicle; quantizing the clean image and the second image to reduce noise and identify differences between the clean image and the second image; identify at least one contour in the identified differences and classify an area defined by the contour as one of a stain, dirt, trash, or another item. Preferably a bounding box is associated with the contour and/or the quantization step includes reducing the colour spectrums of both images to multiple shades of gray. Preferably the vehicle is an autonomous passenger vehicle and based on the classified contour the vehicle may be taken out of service, taken to be cleaned or directed to the next new passenger.
