The influence of high-energy X-ray flash radiography surroundings and capability parameters of CCD instruments to the MTF of CCD was simulated.
模拟了高能X光闪光照相环境及CCD器件性能参数对CCD的MTF的影响。
Thus,the GV regularized algorithm is an efficient image reconstruction algorithm for flash radiography with better performance of noise smoothing and edge preserving.
针对闪光照相图像信噪比低的特点,提出了一种基于广义变分正则化的图像重建算法,该方法采用p-范数取代目前广泛采用的全变分范数作为正则项,构造了用于图像重建的展平泛函,将图像重建问题转化为目标泛函最优化问题,采用固定点迭代法求解图像重建的最优解。
