Raster "threshold" calculation

[MeherELARBI]

I am working with arcmap 10.5 to extract water bodies from sentinel 2 and landsat 8 rasters. I have found on GitHub that otsu method could be a good solution. But I don't want to install other Tools like opencv, etc.

is there a tool in ArcGIS that can automatically calculate the "threshold" value of raster files?

apparently it is available

Threshold—Spatial Analyst module | Documentation 

Binary Thresholding function—ArcGIS Pro | Documentation 

The algorithm used is the Otsu method, which was designed to distinguish between the background and foreground in imagery and create two classes with minimal intra-class variance (Otsu 1979).
