Hello,
I have an image that I am trying to remove surrounding noise from. For example in below image, I want to keep only big black circle and remaining noise must be removed. I have tried thresholding but since every image I take will have a different noise level, the image does not have same black circle all the time because some time I will be left with some noise around it if I don't change the thresholding manually. Is there any way to use manual loops or low pass filter or particle analysis where the system keeps only center big circle and removes everything around it and convert it to white background?
Thanks
