Experiment with non-linear sampling for inverse distortion map #6

Open karolyartur opened 7 months ago

We use linear grid sampling within an upscaled image to distort the images quickly when generating an inverse distortion map. This is relatively slow, and based on the distortion type, a nonlinear sampling might be better suited for this task.

Instead of using simply mgrid here, we could use a function that maps a grid nonlinearly.
