Look for unusual places or features in it, like a valley between humps, "corners" in skewed humps, etc.

for this image and histogram, how can I decide the threshold value?

Looks like there might be one around15 or 20, and another one around 175. Use my interactive thresholding app to see. https://www.mathworks.com/matlabcentral/fileexchange/29372-thresholding-an-image
