根据公式I（n-1）=（1-In）/n 令I11=0计算I1 到I10； 根据公式In=1-nI(n-1) 令I0=0.6321 计算I1到I7； 根据公式X2=a ， 令a=2，计算X的值。(According to the formula I(n-1)=(1-In)/n ，set I11 equals zero，and count I1 to I10. According to the formula In=1-nI(n-1)，set I11 equals zero，and count I1 to I10. According to the formula X square equals a ，set a equals two ，then calculate X )

this function returns the SIFT descriptors DESCR of the SIFT frames P defined on the octave G of the Gaussian scale space.

In computer science, a binary tree is a tree data structure in which each node has at most two children, which are referred to as the left child and the right child. A recursive definition using just set theory notions is that a (non-empty) binary tree is a triple (L, S, R), where L and R are binary trees or the empty set and S is a singleton set.[1] Some authors allow the binary tree to be the empty set as well.

说明：  利用Matlab编写求取4级移位寄存器的M序列 设初始序列为:1 1 1 1 通过一个四级的移位寄存器,其中在第三级有负反馈(一个模二加法),即将序列的第三位和第四位相加(如序列1 1 1 1经移位寄存器第一次移位后为0 1 1 1)的值再赋到第一位. 序列的周期为16.(The use of Matlab to prepare to strike four of the M shift register sequence based initial sequence as follows: 1 1 1 1 4 through a shift register, which in the third grade there is negative feedback (one-mode two adder), the upcoming series third and fourth combined (such as the sequence 1 1 1 1 by the shift register after the first shift for the 0 1 1 1) the value given to the first again. The cycle sequence was 16.)
