A repo for super resolution using basic neural networks. These models can upscale full hd movies to 4k(need to make them faster to run in real time)

Super resoltion is an ill posed problem that doesn't have a unique answer a low resolution image(lr) can correspond to multiple high resolution(hr) images. Specially in over x4 resolution there are lots of lost information, many textures are lost, many different textures can result to the same low resolution pattern.

16x super resolution

4x super resolution

low resolution image

resolution increased with one layer network

resolution increased with two layer network

original high res image

car low res image

car regenerated

car original

16x super resolution from 40x40 to 160x160

low res

regenerated

regenerated 2

low res image

upscaled image

high res original image

low res image

low res image

upscaled image 16x

hi res original image

supermoviechunks notebook scales a full hd movie to a 4k movie. Here are 3 screens from blade runner model(selected ones with problems try to find them :))

full hd image

4k upscaled image

full hd image

4k upscaled image

full hd image

4k upscaled image

full hd image

4k upscaled image i think this one is better than the original not just the resolution but also the colors
