matlab图片二值化

在Matlab中,可以使用两种方法进行图像二值化。第一种方法是使用im2bw函数,该函数已经不建议使用,但仍然可以正常工作。通过读取原始图像并确定二值化阈值,可以使用im2bw函数将图像进行二值化处理。例如,使用im2bw函数将图像转换为二值图像的代码如下:
```matlab
srcImage = imread('原图.jpg');
thresh = graythresh(srcImage);
dstImage = im2bw(srcImage,thresh);
```
另一种方法是使用imbinarize函数,该函数在Matlab 2019版本中被推荐使用。与im2bw函数不同的是,imbinarize函数直接将图像进行二值化,无需指定阈值。下面是使用imbinarize函数将图像转换为二值图像的代码示例:
```matlab
srcImage = imread('原图.jpg');
dstImage = imbinarize(srcImage);
```
以上是两种在Matlab中进行图像二值化的方法,你可以根据自己的需要选择合适的方法进行处理。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
