By contrast, research did find a strong linear relationship between code base size and static analysis defect count.
相反的，研究确实发现代码长度和静态分析漏洞数量的线形关系。

The noise and low contrast of the digitized X ray image made it difficult to recognize defect.
数字化的X射线图像存在噪声且对比度差，给缺陷识别带来一定难度。

Those methods could enlarge the contrast of image and indicate the different change between the defect and the normal signals at different time. And it could be the basis to judge if there was defect.
