In a process for identifying the orientation of a line in an image, a histogram is formed of pixels of the line projected onto an axis. The axis is rotated and a histogram is formed of the pixels projected onto the rotated axis until the histogram includes charateristics indicating that the line is most closely perpendicular to the rotated axis. In a process of detecting a line on a road, an image is acquired of the road, and pixels of the image having characteristics corresponding to characteristics of the line are selected. A histogram is formed of the selected pixels projected onto an axis. The axis is rotated and a histogram formed of the selected pixels projected onto the rotated axis until the histogram includes characteristics indicative of a line. In a process of detecting a lane on a road having left and righ side lines, pixels of the image in a first area of the image at a first orientation and pixels in a second area of the image at a second orientation in the image are selected for selecting pixels associated with the lines. Histograms are formed projected on the first and second axes, respectively, and the axes are rotated until each histogram includes characteristics of a line. Also disclosed is a process of detecting a vehicle in an adjacent lane, systems for performing the aforementioned processes, systems for identifying an object and an input signal, and an interface between an image processing system and a controller.
