A decline in imaging quality will occur when the sampling data of ghost imaging is recorded by binarization. Based on the Otsu binarization, a method named Otsu binary ghost imaging (OBGI) is proposed to enhance imaging quality. Both theoretical and experimental results show that, with an appropriate threshold value, OBGI can enhance imaging quality significantly when compared with ordinary binary ghost imaging, even providing better imaging quality than that of traditional ghost imaging. It is also shown the method is more applicable under the conditions of low-light level and with a complicated object.

使用Otsu算法增强二进制幻影成像的成像质量

当通过二值化记录重影成像的采样数据时，成像质量将下降。基于大津二值化，提出了一种称为大津二进制重影成像（OBGI）的方法来提高成像质量。理论和实验结果均表明，与普通的二元重影成像相比，具有适当的阈值的OBGI可以显着提高成像质量，甚至可以提供比传统重影成像更好的成像质量。还表明该方法在弱光条件下和对象复杂的情况下更适用。
