An expert system based on wavelet transform and radon neural network for pavement distress classification

► An expert system is developed based on wavelet transform and radon neural network (WRNN) for pavement distress classification. ► Classification is performed using the neural network. ► Feature extracted from wavelet decomposition and radon transform. ► The wavelet decomposition and the radon transform have been demonstrated to be an effective tool for feature selecting for neural network.
