Super Upscaling - Waifu2x Test
This is a sample of upscaling from 720p to 4K using Waifu2x-converter-cpp. It's a version of Waifu2x Caffe using AMD vga card.
Quality: Real 4K ≥ Waifu2x ≥ Original Images.
Performance: VGA ≥ CPU (so much), the higher FP32 performance of VGA (same architechture) the lower exporting time and the larger block size the more ram and power hungry.
Compared to Waifu2x-caffe: Waifu2x-caffe has user interface while Waifu2x-converter-cpp doesn't. Waifu2x-caffe can import multiple images while Waifu2x-converter-cpp can't.
Waifu2x-converter-cpp alternatives: Waifu2x-caffe (online), Topaz Giga Pixel AI.
