Most existing techniques detect specific obstacles, such as a pedestrian or a vehicle. Thus, they can\u0027t detect unexpected obstacles on the road. By using subtraction, unexpected obstacles can be detected without the previous knowledge about them. Fist, the proposed method computes the correspondences between the present and the past in-vehicle camera images. Next, the proposed method compensates the gap of the road-surface regions caused by the different running positions, and determines the correspondence of the road-surface regions. Then, obstacles are detected by using spatio-temporal subtraction technique. Experiments were conducted using in-vehicle camera images. The results showed that the proposed method could detect various obstacles on the road satisfactorily.", "subitem_description_language": "en", "subitem_description_type": "Abstract"}]},
