Need Help - Implementing Star Tracker Algorithm on SSA images

[Arshad Geo]

Hi, 

I have a set of SSA images (raw images in tiff format). I have done a task "star centroid detection" using connected component analysis in OpenCV and even got the sub-pixel level accurate centroid coordinates using Gaussian curve fitting. Then, the angle and directional vectors also has been calculated as well.

But, my technical team asking me to get star tracker algorithm which will do three tasks in a go such as Centroid detection, star identification (pattern matching), and attitude determination. Please help me with this. I would be grateful.
