I’m working with an 8-bit grayscale image (0-255) and I want to threshold it so all pixels below 40 intensity are 0 and the foreground is 255 so I can find the foreground.
I’m using the Apply Threshold Module and setting it to output Binary and thresholding method to Manual.
For the Manual Threshold number it gives me an option of 0-1. I’m not sure what this number represents. Is it a percentage threshold based on 0-255? For example, 0.1 = 10% threshold so 25.5 intensity pixels are removed?
Or does it represent something else?
Thanks in advance.
