摘要
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。在图像分解的基础上 ,利用小波分析对工业X射线图像进行去噪和增强处理 ,能够有效地改善图像质量 ,有利于电脑评片的实现。
The noise and low contrast of the digitized X ray image made it difficult to recognize defect. Based on image decomposition, the X ray image was filtered and enhanced by wavelet analysis. Results showed that the image quality was improved and it would benefit the realization of computer interpretation of films.
