comment Identify circles with hough circle
Also, given the size of the circles and the fact that some of them will be skewed, the Hough transform is probably not a very good choice. You would probably do better to look for the specific colors of the markers.

Try looking at the Canny edge map with the same parameters, and see if the circles are even visible there. Once you have the parameters to Canny working well enough, the Hough transform will be more likely to work.

comment could somebody give out some basic examples of this code?
There are other correct ways, but the question asker's version is not correct, since it has "argument c". The version I give is pretty standard, and I don't think I've ever seen another version. Presumably you can rename argc and argv without consequence.

comment How to change dictionary from one format into another?
If you want to do a single pass over the files, you would be holding all 25 dicts in memory at once anyway, so the memory usage should be the same.
