给定栅格图象及其变形后的栅格图象，请你首先确定各栅格交叉点的位移，然后采用控制栅格的方法编写实现图象几何校正的程序(Given raster images and raster images after deformation, you first determine the grid cross-point displacement, and then using the control method of preparation of raster realize image geometric correction procedures)

递归法求解整数划分。 整数划分，是指把一个正整数n写成如下形式： n=m1+m2+…+mi （其中mi为正整数，并且1 <= mi <= n），则{m1,m2,...,mi}为n的一个划分。 如果{m1,m2,...,mi}中的最大值不超过m，即max(m1,m2,...,mi)<=m，则称它属于n的一个m划分。这里我们记n的m划分的个数为f(n,m) (Recursive method integer division. Integer division, refers to a positive integer n written as follows: n = m1+m2+ ...+mi (where mi is a positive integer, and 1 < = mi < = n), then {m1, m2, ..., mi} is a division of n. If {m1, m2, ..., mi} does not exceed the maximum value of m, i.e., max (m1, m2, ..., mi) < = m, m n is said that it belongs to a division. Where m is the number of division n our mind is f (n, m) )

turbo码研究人员不可避免的吴宇飞的升级版程序，对turbo码的算法和其他思想的结合，仿真效果对学好turbo码是一个捷径(turbo codes researchers an upgraded version of inevitable Wu Yufei procedures, turbo code algorithm and a combination of other ideas, simulation results of turbo code is a shortcut to learn)

说明：  为MATLAB中的图形增加标签，从而可以有效地表示图形意义，防止读不懂图的情况( BWLABEL supports 2-D inputs only, whereas BWLABELN support any input dimension. In some cases you might prefer to use BWLABELN even for 2-D problems because it can be faster. If you have a 2-D input whose objects are relatively "thick" in the vertical direction, BWLABEL will probably be faster otherwise BWLABELN will probably be faster.)
