given an image that has been segmented into smaller regions (superpixels). How to repeat same content (color pixel values) of one region in the image (e.g., superpixel with id = 1) into another one (e.g., superpixel with id=2) if the sizes of them are slightly different,

"interpolation or padding are allowed".

Well the shapes of each superpixel will be different so what are your plans regarding the different shapes?

Anyway, for what it's worth, attached is my demo for copying and pasting irregularly shaped regions.

thanks a lot for your answers,

I like your copy_paste_image_freehand example...

It is near to what I want to achieve, I only still need to deal with the size differences between the two superpixels, since i have the mask for both of them I just want to compensate any pixels that does not have corresponding pixels in the first superpixels by interpolation or padding or any other idea?
