I'm working on a project and I need to identify the number of grains in pictures with several of these grains touching, overlapping. Can someone help me with this ? Thanks a lot

Train a model of object detection: You can train some model like object detection (YOLOv5) or some other and calculate the count.

This is a very broad question so I will give you a broad answer, you could train a computer vision model, or you could use simple image processing using open cv:

• Learn about color threshholding: everything that is not the color of the grain becomes a black pixel, everything else becomes a white pixel.

• Learn about MorphologyEx, to disconnect connected grains.

• Get the numbers of contours of white objects in the blacked out image.

All of those are simple google searches that will achieve what you desire. Using open CV.
