说明：  寻找三次样条多项式需要求解大量的线性方程。实际上，给定N个断点，就要寻找N-1个三次多项式，每个多项式有4个未知系数。这样，所求解的方程组包含有4*(N-1)个未知数。把每个三次多项式列成特殊形式，并且运用各种约束，通过求解N个具有N个未知系数的方程组，就能确定三次多项式。 (find cubic spline solving polynomial need a lot of linear equations. In fact, given N breakpoints, it is necessary to look for N-1 cubic polynomial, each with four polynomial coefficients unknown. Thus, by solving the equations contain 4* (N-1) unknown. Each cubic polynomial Timing special form, and use of various constraints, by solving N with N unknown coefficient equations, we can identify three polynomial.)

源码 此程序主要是对二值图像进行操作有效 如对灰度图像进行操作只需要修改部分代码既可以(The main source of this procedure is the binary image to operate effectively on the gray image to operate only need to modify some of the code can)

opencv里面像matlab那样显示直方图，解决了opencv没有显示直方图的缺陷。(opencv as it shows as histogram matlab to solve opencv histogram did not show defects.)

Converts a floating point value to IEEE 754 32 bit binary representation. Sign Bit: 1 Exp: 2 to 9 Frac: 10:32 Single-precision floating-point format is a computer number format that occupies 4 bytes (32 bits) in computer memory and represents a wide dynamic range of values by using a floating point. In IEEE 754-2008 the 32-bit base 2 format is officially referred to as binary32. It was called single in IEEE 754-1985. In older computers, other floating-point formats of 4 bytes were used. For example, the 32-bit floating point bit pattern 1 01111101 00101100000000000000000 is interpreted as the following: (− 1)1 × (1 + 0.34375) × 2(125–127) = -1.34375× 2− 2 = -0.3359375 ​
