The present invention relates to a method for object detection and ranging within a vehicles rearward field of interest which includes an algorithm to translate images provided by an imaging device. An image device provides images to a processor which divides the images into groups of rows of pixels. The rows are processed by the algorithm which includes assigning each pixel in the rows to an object. The translation of the image from outside of the vehicle is provided to the vehicle operator and includes the tracking of location and dimensions of multiple objects within the viewing range.
