What's the image resizing impact on the accurate x-y location of a point?

Hi all, I'm interested in X-y location of a point on an image. If I interpolate the image to be 1000 by 1000 pixels, then downsample it to 200 *200 pixels. Then measure X-Y location of the point....

Why does some metric (cost function) require very short step size of the optimizer to give good registration results?!?

Hi All, If the metric ( cost function) is very sensitive to the step size of the optimizer and the number of iterations, what does it mean?!. Does that mean the metric has a limit then the...
