该文提出一种改进的最大熵法、分别从①应满足的约束条件、②J的凹凸性,③递推公式④初值。⑤算法的收敛性。⑥复杂度。⑦选代步长。⑧分辨率与步长初值及Q最后值的关系等方面作了数学分析,提出了处理程序,实验表明:图象的分辨率受最后Q值的影响最大,其次是初值,然后是步长,与信噪比也有关,信噪比越大,复原效率越好。该文认为,改进法得出最可能的复原结果。
In this paper, an improved maximum entropy method is proposed, which consists of ① the constraints that should be satisfied, ② the concavity and convexity of J, and ③ the initial value of formula ④. ⑤ algorithm convergence. ⑥ complexity. ⑦ election step. ⑧ resolution and the initial value of step and the relationship between the final value of Q made mathematical analysis, put forward the processing procedures, experiments show that: the resolution of the image by the last Q value of the greatest impact, followed by the initial value, and then step Long, and the signal to noise ratio is also relevant, the greater the signal to noise ratio, the better recovery efficiency. The article argues that the improved approach yields the most likely outcome of recovery.
