How to detect the desired feature points automatically ??

Hi I have question that how to automatically detect the points(in yellow) of the image attached. I want to find the x,y values of that points and I have sequences of image and the points position will change from each frame. So, I need an automatic way to detect these points from each image. Each image will almost have the same shape. And If anyone know the best way to find the laser edge in image. Thanks

Are those yellow crosses in each image or are they just for marking the points you want to detect? Because if you have them in every image, just detect yellow color.

But i assume you want to find the start, highest point and end of the arc in the middle. For the highest point you can look for the extrema, the pixel with the highest y value. For the other two you could cut the pic in half at the middle point, then flip it and search for the top right point in the left image and for the top left in the right image.
