Web20 jul. 2009 · It's pretty simple to use the code. Otsu Thresholding works on grayscale images. So firstly, we have to convert our image into a gray scale one. After that, we can obtain our Otsu threshold value by solving for maximal t. Finally, we threshold our image using this t value. In short, the usage looks like this: C#.
