基于最大熵估计的方法能从不完全和带噪的观测数据对信号进行估计,在许多领域有重要应用。本文比较详尽地讨论了最大熵在用不完全投影数据重建图象中的应用,就其在重建图象的质量以及抗干扰能力等方面的特性作了研究,并给出实验结果。
The method based on maximum entropy estimation can estimate signals from incomplete and noisy observation data and has important applications in many fields. This paper discusses in more detail the application of maximum entropy in reconstructing images by incomplete projection data, and studies its characteristics in reconstructing the image quality and anti-jamming capability. The experimental results are also given.
