In OpenCV Stitching pipeline, there is a block named "Final Pano Scale Estimation". Can anyone please explain its functionality and how to calculate the scale? I know that OpenCV resize the input image being used for stitching and after calculating the required transformation/information it rescales the output (These are related the Resize Block). I was exploring the Cylindrical Panoramas, in cylindrical panoramas reverse mapping is performed to avoid the holes, "warpers_inl.hpp" file has the information about the backward mapping ((mappingbackward))function, the input to this function is u, v, x and y, the very first lines of the function divides the u and v values with the scale factor. How this scale factor is computed? It will be really helpful if someone can help on this Many Thanks.
