MATLAB的几个作图技巧MATLAB的几个作图技巧(MATLAB)

很好的书，我找了好长时间才找到的，大家要去看看，肯定会有收获的！(Very good book, I found a good long time to find everyone going to look at, there will certainly be harvested!)

基于傅立叶－梅林变换的matlab图像配准程序，可以灵活设置待配准图像的大小及旋转角度等，配准前可以选择多个参数控制配准结果，可以显示配准后的图像及图像间的具体变换参数以及中间结果等(Based on Fourier- Mellin transform matlab image registration procedures, registration can be flexibly set the image size and rotation angle, registration before you can select multiple parameter control registration results, you can display the images and post-registration between images specific transformation parameters and intermediate results)

梯度下降法是最早最简单，也是最为常用的最优化方法。梯度下降法实现简单，当目标函数是凸函数时，梯度下降法的解是全局解。一般情况下，其解不保证是全局最优解，梯度下降法的速度也未必是最快的。梯度下降法的优化思想是用当前位置负梯度方向作为搜索方向，因为该方向为当前位置的最快下降方向，所以也被称为是”最速下降法“。最速下降法越接近目标值，步长越小，前进越慢。(The gradient descent method is the earliest and most simple and most commonly used optimization method. The gradient descent method is simple to realize. When the objective function is a convex function, the solution of the gradient descent method is a global solution. In general, the solution is not guaranteed to be the global optimal solution, and the gradient descent method is not necessarily the fastest. The optimization idea of gradient descent method is to use the current position negative gradient direction as the search direction, because the direction is the fastest descending direction of the current position, so it is also called the steepest descent method. The faster the slowest descent approach is closer to the target, the smaller the step, the slower the progress.)
