| 摘 要： | 应用基于小波变换的图像分解和重构方案可以进行公路路面裂缝的检测与识别。首先对路面图像进行多分辨二维离散小波分解,根据在每个尺度2j上小波系数模最大值和相位(梯度方向)这两个分量的大小确定边缘的位置,进一步变换小波分解系数,达到去除噪音,加强裂缝边缘的效果。并通过实验分析和讨论了不同的小波基、不同分辨率水平、重构中使用的分解子图像对路面图像裂缝分割的影响,最后用简单的阈值技术生成二值图像,把裂缝从背景图像中分离出来。 |

| Abstract: | The image decomposition and reconstruction programs based on wavelet transform are applied to the detection and recognition of pavement cracking. Firstly,2-D discrete wavelet multi-resolution decomposition is carries out on the image of the pavement. The location of the edge is determined by the size of two components,that is,the phase (gradient direction) and local modulus maxima of the wavelet transform at different decomposition levels. The wavelet decomposition coefficients are further transformed to re... |
