How can I apply Otsu’s threshold method to a Raster in QGIS for reduction of a gray level image to a binary image?

Upon Research, simpler workflow is possible in ArcGIS. Add Raster to ArcMap. Navigation: Windows > Image Analysis. Select Raster in Image Analysis Menu. Under Processing > Add function. Right click on Raster > Insert function > Binary Thresholding function Link: desktop.arcgis.com/en/arcmap/10.3/manage-data/raster-and-images/… – HansrajR Jan 9 at 6:11

You can install and use the OpenCV module in QGIS python environment (https://opencv-python-tutroals.readthedocs.io/en/latest/py_tutorials/py_imgproc/py_thresholding/py_thresholding.html).
It will require some coding but the above link will help. In ArcGIS getting the desired result is difficult to achieve as lots of customization is required.

1Yes. You can run the code in the Python Console of QGIS 3. This post might help gis.stackexchange.com/questions/355217/… – Priyanka Pandey Jan 9 at 18:07
