1. A classifying system for a host vehicle comprising: at least one sensor coupled to the host vehicle and adapted to detect boundary data of an obstacle, said sensor further adapted to generate an obstacle signal in response to said boundary data; and a controller coupled to the host vehicle and adapted to receive said obstacle signal, said controller adapted to generate a bounding box for said obstacle in response to said obstacle signal, said bounding box including at least one vertical pixel corresponding to a maximum height of said obstacle and at least one horizontal pixel corresponding to a maximum width of said obstacle, said controller including obstacle classifying logic adapted to classify said obstacle in response to said height and said width.
