Hi
i have some image where i need to find out the black holes, the prob is we could able to see some light difference in all the images so we cant able to set the threshold value ...
i tried histogram equalization n normalization, but for some images it is working, not for all images - How can i process further ?
For Ex :
1st Image
Image Background value - 40 45 2 RGB
Black hole value - 18 17 0 RGB
2nd Image
Image Background value - 20 16 2 RGB
Black hole value - 14 15 0 RGB
---------------------------------
based on 1st image if i set as below 20 as my threshold value, it working for these kind of similarly images but it goes wrong when we running 2nd image ..
Any help would be helpful ,
Thanks
