因此提出了改进的偏折层析滤波反投影算法，数值模拟表明，改进算法在有效抑制倾斜现象的同时，对重建结果不会造成明显的失真。
Results show that the effect of projection noise on the reconstructed fields is represented by a slope function related to the filter used in deflection tomographic filtered back-projection algorithm.
基于动力系统模型的局部投影非线性降噪算法，对混沌信号和一大类非平稳信号具有明显的降噪效果。
The algorithm of local projective nonlinear noise reduction based on nonlinear dynamic system is more effective for noise reduction of chaotic signal and non-stationary signals.
在持续改进的精神下，这些投影片可能有所更动，如果注解有很明显的变更，我将会新版本带到课堂上。
In the spirit of continuous improvement, the slides may also be changed. If I make dramatic changes to the notes I will try to bring new copies to class.
