In one implementation, a method receives a clean image of a vehicle interior and a second image of the vehicle interior after a passenger has occupied the vehicle. The method quantizes the clean image and the second image to reduce noise and identifies differences between the clean image and the second image. Additionally, the method identifies at least one contour in the identified differences and classifies an area defined by the contour as one of a stain, dirt, trash, or another item."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Stain and trash detection systems and methods","description":"Example stain and trash detection systems and methods are described.
