A vision-based object detection decision-making system for a vehicle includes multiple vision sensing systems that have vision receivers and that generate an object detection signal. In order to arrive at an improved signal to noise ratio of a bar code symbol being read, a processor produces two signals at respective first and second channels, the signal in the second channel being buffered and merged with a later signal in the first channel allowing time averaging out of the noise portion of the signal and enhancement of the information portion of the signal. The profile of the trench is modified to provide a first width at the aperture of the trench and a second width at the bottom of the trench. A single broadcasting of each network advertisement to all television systems is enabled in the present invention by broadcasting each advertisement with a network identifier to all television systems. Image processing is carried out on the image data S0 according to the image processing conditions G and processed image data S1 are obtained.
