In this method, first, the gray-scale image of the molten pool is obtained according to the fractal-based discrete Brown random field theory. Next, the connected domain is detected based on the binary morphology theory and is then used to remove the noise and obtain the target image. Moreover, the successive edges of the image are obtained by means of the Open-Close operation on the basis of the mathematical morphology theory.

该方法利用分形理论中的离散分数布朗随机场理论得到按分形维分布的熔池灰度图像，然后利用二值形态学中的连通域检测去除噪声并得到目标图像，进而利用形态学中的开运算和闭运算得到图像的强连通边界。
