图像的二值化处理就是讲图像上的点的灰度置为0或255，也就是讲整个图像呈现出明显的黑白效果。即将256个亮度等级的灰度图像通过适当的阀值选取而获得仍然可以反映图像整体和局部特征的二值化图像。
进行二值图像的处理与分析，首先要把灰度图像二值化，得到二值化图像，这样子有利于再对图像做进一步处理时，图像的集合性质只与像素值为0或255的点的位置有关，不再涉及像素的多级值，使处理变得简单，而且数据的处理和压缩量小。为了得到理想的二值图像，一般采用封闭、连通的边界定义不交叠的区域。所有灰度大于或等于阀值的像素被判定为属于特定物体，其灰度值为255表示，否则这些像素点被排除在物体区域以外，灰度值为0，表示背景或者例外的物体区域。如果某特定物体在内部有均匀一致的灰度值，并且其处在一个具有其他等级灰度值的均匀背景下，使用阀值法就可以得到比较的分割效果。如果物体同背景的差别表现不在灰度值上（比如纹理不同），可以将这个差别特征转换为灰度的差别，然后利用阀值选取技术来分割该图像。动态调节阀值实现图像的二值化可动态观察其分割图像的具体结果。
函数原型
cvtcolor()
RGB空间内的变换，例如添加/删除Alpha通道，反转通道顺序，转换为16位RGB颜色（R5：G6：B5或R5：G5：B5），以及使用以下方式转换为灰度/从灰度转换：
从RGB图像到灰色的转换是通过以下方式完成的：
cvtColor（src，bwsrc，cv :: COLOR_RGB2GRAY）;
但是在实际的imread得到的图像为BGR,所以使用的函数是:
cvtColor(m_srcImage, m_grayImage, COLOR_BGR2GRAY);//图像格式转换adaptiveThreshold()
void cv::adaptiveThreshold | ( | InputArray | src, |
| | OutputArray | dst, |
| | double | maxValue, |
| | int | adaptiveMethod, |
| | int | thresholdType, |
| | int | blockSize, |
| | double | C |
| ) | |
#include <opencv2/imgproc.hpp>
对数组应用自适应阈值。
该函数根据公式将灰度图像转换为二进制图像：
T.（x ，y） 是为每个像素单独计算的阈值（请参阅adaptiveMethod参数）。
该功能可以就地处理图像。
参数
SRC | 源8位单通道图像。 |
DST | 与src具有相同大小和相同类型的目标映像。 |
包括maxValue | 分配给满足条件的像素的非零值 |
adaptiveMethod | 要使用的自适应阈值算法，请参阅AdaptiveThresholdTypes。该BORDER_REPLICATE | BORDER_ISOLATED用于处理边界。 |
thresholdType | 阈值类型必须是THRESH_BINARY或THRESH_BINARY_INV，请参阅ThresholdTypes。 |
BLOCKSIZE | 用于计算像素阈值的像素邻域的大小：3,5,7等。 |
C | 从平均值或加权平均值中减去常数（请参阅下面的详细信息）。通常情况下，它是正数，但也可能为零或负数。 |

参考原文：
1. 代码中我生成灰度图的时候使用图片格式为 QImage::Format_Grayscale8 ，Qt助手中给出的解释The image is stored using an 8-bit grayscale format可以看出，这种图片中用8-bit存储灰度值，所以每个像素只有1字节；这里我也试过 QImage::Format_RGB888 格式（The image is stored using a 24-bit RGB format (8-8-8)），这时每个像素有3个字节，这里牵扯后面代码中有不同的地方。
实验中,除了展示原图像以外,QImage::Format_RGB888都会使程序崩溃.
后面对图像的二值化处理都是在灰度图的基础上完成的,所以都使用了 QImage::Format_Grayscale8格式.

以下是个待解决的bug!
尝试加入了一个新控件dial
编译通过,运行就崩溃:
OpenCV: terminate handler is called! The last OpenCV error is:
OpenCV(4.1.0) Error: Assertion failed (src && dst && count > 0) in FilterEngine__proceed, file D:/opencv/opencv/sources/modules/imgproc/src/filter.simd.hpp, line 220
Invalid parameter passed to C runtime function.
至今没有解决感到很迷惑,然而这个控件不关联blocksize和delta的时候整个程序都可以运作成功,二值化函数不是可以就地的吗.....
如果有大佬明白还望指点迷津,感谢!!!
