“…When using color information in road sign detection methods, change in lighting, strong illumination and adverse weather conditions can result in problematic changes. These problems were overcome by using Color models such as HSV [14], [9], [11], [25], [26], YUV [13], YCbCr [18,38,40] and CIECAM97 [15]. Although color based approaches produce faster results in most of the cases it reduces the detection rate in the cluttered environment.…”
