The waifu2x-ncnn-vulkan image looks distinctively better than the others. It also appears to be non-functional or not doing a very good job. Waifu2x_glsl lacks PNG transparency support. Note: RealSR can only do x4 so the RealSR image on the left is down-scaled by 50%. Waifu2x-ncnn: waifu2x-ncnn -s 2 -i agt_family.png -o agt_: Waifu2x_glsl: waifu2x-glsl -s 2 agt_family.png -o agt_family.waifu2x_glsl-2x.png : ImageMagick convert: convert agt_family.png -resize 256 agt_ This shows where waifu2x's emphasis on 2D anime images during the training of the neural network comes in. RealSR produced weird artifacts regardless of whether I flattened the image or not. Adding a white background with GIMP or other software will usually produce better results, as was done here. Waifu2x has trouble with especially small images with a lot of feathered PNG alpha transparency. The Kids theme, released in 2003, did not include any SVG images - only icons up to 128x128.
