What upsampling methods are there?
I've got a model, which tries to upsample it, without losing any quality. What upsampling methods are there? I would like to know more about interpolation method as well.

You can use regular upsampling methods, which are implemented in different libraries like OpenCV, Tensorflow, Keras, Pytorch etc. It is a simple upsampling with different interpolations: Bilinear, Nearest, Bicubic, Lanczos etc.
