Circle detection in CTscan
2 visualizzazioni (ultimi 30 giorni)
Dear specialists, Currently, I have to detect some circles from CT scan images. The sample is as below
The radius range is from 5-110, so I tried to divide this range into several smaller intervals. However, the results is not adequate. Could anybody please help me to detect them ? Thank you very much.

This code looks really useful. I tried to use it for the detection of pores in the attached picture. As you can see, especially in the center, the pore spaces are widely connected, so a distinction would be needed. Basically i would like to fit in circles into the pore spaces to get a pore size distribution. Using your proposed code as it is does not help in this case. Could you suggest which parameters to play with in order to make it fit better for less obvious cases like mine?
