Thank you so much for your comment. I am not working with Iplimage, I just said that I found a library for iplimage and not for mat . My problem is now solved thanks to your answer.

Hello,

I would like to display some axes on an image ( ordinate and abscissa ), I woud like to know if there is a function in opencv that allows me to do it ? ( I am working with Mat, I saw a library for iplimage )

Thanks for answering. I want to know the distance between the centers. It's the idea that circle are recurrent, so they probably have a frequency so probably I could use a DFT to get those infos. I guess we can forget this sentence, I meant that Hough will find a circle and then the closest, and that I could use that to get the distance.

Hello,

I want to draw a circle that allows me to collect informations about my image. I have done a DFT, and I want to get the information of low and high frequencies with a circle. The question is " how can I use the circle as a system of mesure ?" If someone could explain it to me, it will be great.

I am trying to do a program that can recognize circle and use the informations to build a data.

The part that I am trying to build now is the "minimum distance between two circles" . I have 6800 circles on one picture, so it has to be precise.

My idea was to get the position of the first circle (i=1) and the position of the second circle (i=2). I guess it will be the fastest but I don't think it will be the minimum. I have the hope that maybe Hough function is detecting one circle and then the closest that's why I ask this.

Second idea get all the position and find for each position the closest point. I guess it is the best one but it could be slow no ? ( already Hough function makes my program slow)

The thing is that I don't have any idea of the function that I could use.

How to get the position of each circle (center) ?

Hope you can help me
