MATLAB 数值计算
- 科研和工程计算可分为数值计算和符号计算两类。数值计算具有适应性强、应用广泛的优点。MATLAB凭借其卓越的数值计算能力而称雄世界。随着科研领域、工程实践的数字化进程的深入，具有数字化本质的数值计算显得愈益重要。 今天计算机几乎已经普及到每个从事工程和科研的从业人员，普及到每个正在接受理工科培养的学生。计算机软硬件的普及使人们拥有了前所未有的计算潜能，激发了人们质疑旧方法尝试新算法的欲望，鼓舞了人们用新计算能力试探解决实际问题的雄心。 本章内容显著不同于常见的数值计算教科书。本章的讨论围绕
EMM盲运动模糊图像的恢复
- 摘 要 盲图像恢复的主要困难是信息不足，而为了恢复图像和确定点扩散函数需要适当的先验知识。解决这个问题的法、 法以及正则化方法等。但是这些方法的计算量都太大，针对上述方法的不足，文章提出了一种恢复图方法有图像的新算法，它通过恢复残差的最小化和后验概率的最大化来估计参数和恢复图像。其中，巧妙地利用了最陡梯度法和 共轭梯度法的迭代求解。对由于运动造成的模糊图像，可以明显地改善图像的质量，实验结果证明，在对模糊操作没有严格限制的情况下，仍可得到较好的恢复图像。,： : 2$*/<$ I?E
