针对传统Chan-Vese(CV)模型对公路路面破损图像分割的局限性，将图像梯度信息引入CV 模型，利用路面破损区域纹理与背景的

不同，对图像进行分割。引入梯度阈值，将图像的灰度信息和纹理信息相结合，从而使分割方法更具灵活性-Distress image segmentation on the road surface limitations for traditional Chan-Vese (CV) model, the introduction of image gradient information CV model, the use of the road surface texture and background of the damaged area of ​ ​ the different image segmentation. To introduce gradient threshold, combining image intensity and texture information, so that the segmentation method more flexibility
