Abstract : This paper deals with a new approach for crack detection on road surface images using the wavelet transform combined with grey level morphology and segmentation. The pave-ment analysis context is briefly presented. Two image proc-essing methods have been developed. Results obtained with “laboratory images” and “road images” are presented and discussed.
