In this paper we present a statistical approach for the detection of road signs present in an image by using only color related information. IndexTerms—Detection, road signs, directional T2 Hotelling, RGB, HSV

Step-down testing procedures for the Hotelling T2 problem are considered. We show that the step-down procedure proposed by S.N. Roy, R.E. Bargmann, and J. Roy is inadmissibleamonginvariantprocedures (for a suitable invariance group) in many situatiqns, includiItgallthosefor which more than two steps are contemplated. We also show that in most cases, the power of the step-down procedure decrease...
