I want the theorotical explanation of the imresize function for downscaling the image. I have referred to the following

https://blogs.mathworks.com/steve/2015/10/20/image-resizing-geometry/?s_tid=srchtitle
The article "General Filtered Image Rescaling," by Dale Schumacher, in Graphics Gems III, Morgan Kaufmann, 1994.

I have understood how the indices are calculated in imresize function, but I am confused about how the weights are calculated in imresize function.
