I would like to interpolate this picture (not by increasing the resolution).
I filled the areas with fillPoly() by providing the corners of the Polygon and displayed it with via colorMap. But now I would like to “smooth” / Interpolate so that I do not have these strict and hard boundaries anymore.
I was looking for a simple function provided by opencv like reMap or convertMaps. But I am not quite sure wether these functions will work. (I could not get them working).
Do you guys have a hint for what I am looking for? Or do I have to write a function by myself.
