DIGITAL IMAGE ANALYSIS OF CRACKSONTHE CONCRETE SURFACE BASED ON THE GABOR WAVELET TRANSFORMATION

Abstract

 The standard method of investigation of cracks on the concrete surface is usually visual inspection. However, the method has many problems such as inspection data spread, oversight, lack of objectivity and data quantification. Therefore, digital image analysis of concrete cracks is developed from the view point of efficient, automatic and quantitative inspection. For accuracy improvement on the extraction of cracks, the two-dimensional Gabor wavelet transformation method is applied to digital image analysis. Furthermore, it is clarified that the method is effective in cracks extraction from application of this method to the inspection of structure.
