Application of Wavelets to Measurement of Concrete Cracks and Discrimination of the Road Condition

Abstract

In this paper, we propose a method for image processing by applying vector field theory and vector wavelets transform. The process of this method consists of making vector data from pixel value and multi resolution analysis for the vector data. The method is applied to measurement of concrete cracks and discrimination of road condition. The method can reduce the quantity of information about spots and texture of illumination, resulting in exactly extracted cracks. With the method, we can decide the surface condition of road quantitatively.
