摘要
本文针对闪光照相 CCD成像图像噪声多的特性 ,提出用阈值法、多剖线平均法和多项式曲线拟合法对图像中的白斑噪声、涨落噪声和其它噪声进行处理 ,取得了较好的
In view of the many noises in the radiographic CCD image, we proposed and studied three noise clearing methods: threshold, many profile averaging and curve-fitting. The white spot noise, quantum noise and other noise in the image were processed and a good result from MTF measurement is achieved.
