摘要
提出一种用于印刷缺陷检测的图像对准算法。对准抽样点取自图像边缘 ,提高了算法效率 ,降低了运算量。同时引入遗传算法 ,避免陷入局部最优。实验表明 ,该算法能对平移。
A registration method for defect inspection of printing matter is proposed in this paper. The sampled pixels are gotten from image edge,which can improve the efficiency and reduce the computational complexity.Genetic algorithm is used to find the global optimum results.The experimental results show that the proposed registration method can efficiently register images that are changed in translation,rotation and scale.
