Suppose I have a 640x480 pixel video chip and would like to find star images on it, possible planets and the moon. A possibility of noise exits, or bright pixels. Is there a known method for finding the centroids of these astro objects?
You can threshold the image and then cluster the pixels in objects. I've done this on occasion using my own software, but I think there might be something in scipy/ndimage that does the same. Someone here will know. Chuck
