针对毛玻璃型肺结节成淡淡的模糊影,不容易用肉眼观察到,并且其灰度值介于肺实质和血管之间的特点,提出一种基于带通滤波器的毛玻璃型肺结节检测方法.首先用OTSU算法分割肺实质,然后用带通滤波器检测毛玻璃型肺结节.实验表明,此检测方法在所需运行时间和敏感性上都优于现有方法.

Ground glass opacity nodule is fuzzy and could not be observed by eyes,and its grey value is between the lung parenchyma and vessel.Aiming at these factors,a method of detection is put forward based on band-pass filter.Firstly,lung parenchyma is segmented by using OTSU algorithm;then,ground glass opacity nodule is detected based on band-pass filter.Experiments show that the proposed method is better than existing methods in required running time and sensitivity.
