     Parallel processing architecture brings advanced vision applications
     to today's cars

     Technologies now on the road enable automotive design engineers
     to implement robust and powerful recognition algorithms, while meeting
     the stringent power consumption and operational constraints associated
     with automotive design.

Safety continues to be one of the key concerns in automotive design.
     In addition to keeping drivers and passengers safe, automotive manufacturers
     are looking for ways to protect people outside the car-such as bicyclists
     and pedestrians. While airbags and seat belts are designed to provide
     protection inside the vehicle, accident avoidance equipment, through
     applications such as vision-based warning systems, could provide
     the ultimate solution for protecting lives both inside and out.




     Analysis shows that the vast majority of accidents are caused by
     human error or misjudgment. Automotive electronics that could monitor
     driving conditions and warn a driver at the onset of a hazardous
     situation could go a long way in preventing and mitigating human-induced
     accidents.



     When vision-based warning systems for drivers were first introduced,
     acceptance from consumers was limited, mainly due to high costs
     and a lack of reliability related to false warnings and such. Systems
     have improved dramatically in recent years, and new vision systems
     are now being introduced by companies such as Toyota for its flagship
     Lexus LS460 (below). Current technologies enable automotive designers
     to implement robust and powerful recognition algorithms while meeting
     the stringent power consumption and operation constraints associated
     with automotive design.
