<p>Method of Processing Images and Apparatus A method of processing an image comprises of a region of a highway in front of the vehicle captured using an imager having a two dimensional array of image capturing pixels, the array comprising a first set of pixels substantially independent of hue and a second set of pixels dependent on a limited range of hues, producing a first image where each pixel is assigned a value derived from the first set of pixels, producing a second image where each pixel is assigned a value derived from the first set of pixels and the second set of pixels, identifying for at least one pixel in the first image a first intensity change value indicative of the difference between that pixel and at least one adjacent pixel,identifying for a corresponding pixel in the second image a second intensity change value indicative of the difference between that pixel and at least one adjacent pixel, and forming a combined image using a defined set of combination rules to assign a value to the corresponding pixel in the combined image which depends on the first and second identified intensity change values for that corresponding pixel.</p> |
