Hello,

I'd like to rotate my circular image based a detected feature or template image.

so my images will be exactly the same rotated.

lets say this is my original image

when I give this image as input.

it should detect small circle's template or feature then rotate it while those two images will be same.

Use HoughCircles to find booth circles and compute the Rotation angle. Then use getrotationmatrix2d to get the Rotation around the Center of the large Circle With the just computed Rotation an use warpaffine to apply it to the image.
