前面简单学习识别文字，只要图片有点问题，很难识别正确，要想好的识别要对对图像进行预处理。
VectorOfTesseractResult 类
构造函数：
public VectorOfTesseractResult() //空对象
public VectorOfTesseractResult(int size)//相当于数组大小
public VectorOfTesseractResult(TesseractResult[] values)//以TesseractResult[]值初始化对象

基本属性：都是只读，当然类数组属性不变。
public struct TesseractResult//用于存取识别的结果
public float Cost
public int Length
