分水岭分割算法在电成像测井资料中的应用
|
摘要
针对采用阈值分割算法分割图像时图像背景与孔洞存在粘连,背景存在干扰时分割效果不理想的情况,提出利用分水岭分割算法对图像进行初始分割,再选取合适的阈值对图像进行二次分割。上述方法均在VS2010上实现,编写图像分割程序,并对四川盆地某井电成像测井图像进行分割。研究结果表明,该算法分割出来的孔洞区域完整、边界清晰,且能较好地压制噪声。
Aimed at the shortages of threshold segmentation,such as the cavities sticks with background,and the bad effects of segmentation when there exists noises. In this case,this paper proposed watershed segmentation algorithm to segment the images initially. All these method have already been implemented by VS2010. The segmentation of electrical image logging data in Sichuan indicates that pores are integrated and its boundaries are explicit. And it also indicates that this method can suppress noise well.
