Hi Gwyddion users, I have a probably rather simple question to you but unfortunately so far i could not solve by myself. I have a series of stm images taken at the same coordinates. By following a feature on several stm images I want to correct the drift based on the assumption of a constant drift velocity. Assuming the distorted image would have to be transformed by X' = X - Vd * t(x,y) , where X' is the corrected image, X is the distorted image, Vd is the calculated drift velocity and t(x,y) is the time for each data point. The solution will result in a polynomial equation. Its coefficients calculated from coordinate ranges [0,1] i want to put in the polynomial distortion dialog ( Data Process → Correct Data → Polynomial Distortion ). Now i have two questions.
Am i doing this correctly? Probably this is a rather simple method but my images don't seem to improve as expected. The undistorted image is only partially visible on the window due to the transformation. Is there a way to see the whole image?
