Abstract: The Graph Cuts segmentation algorithm is not sufficient to segment Printed Circuit Board (PCB) images with non-uniform gray level and complicated inner structure. A new interactive Local Progressive Graph Cuts (LPGC) segmentation method that modeled local constrained energy into a graph cuts framework was presented in this paper. The local constrained energy was adaptively generated by modeling the users additional information behind the interaction, such as the location of the seed, the class of the seed and the relative position between the seed and previous result. Through a comparison of different PCB image segmentation experiments, the results demonstrate the proposed method has better performance compared with the-state-of-art method such as graph cuts in terms of segmentation accuracy, controllability, and user experience.

摘要: 针对图割算法对灰度不一致且结构复杂的印刷电路板(PCB)图像不能有效分割的情况,提出一种新的交互式局部渐进图割方法。通过分析用户交互过程中提供的信息生成局部约束能量项,并将其融入图割模型中,其中局部约束能量项依据用户添加的种子点的位置、类型以及与前一次分割结果的相对位置等信息自适应地生成。通过对多组锥束计算机断层成像(CBCT)系统采集的PCB图像进行分割实验,结果表明与经典的图割算法相比,所提方法能得到更准确的分割结果、更好的可控性及用户体验
